Section 201 Oxidation and Reduction

In Chapter 10 you learned that a chemical reaction can usually be classified asone of five typesmdashsynthesis decomposition combustion single-replacementor double-replacement In this chapter yoursquoll investigate a special characteris-tic of many of these reactionsmdashthe ability of elements to gain or lose electronswhen they react with other elements You experimented with this characteristicwhen you did the DISCOVERY LAB

Electron Transfer and Redox ReactionsOne of the defining characteristics of single-replacement and combustionreactions is that they always involve the transfer of electrons from one atomto another So do many but not all synthesis and decomposition reactionsFor example you studied the synthesis reaction in which sodium and chlo-rine react to form the ionic compound sodium chloride

Complete chemical equation 2Na(s) Cl2(g) 0 2NaCl(s)

Net ionic equation 2Na(s) Cl2(g) 0 2Na 2Cl(ions in crystal)

In this reaction an electron from each of two sodium atoms is transferred tothe Cl2 molecule to form two Cl ions An example of a combustion reactionis the burning of magnesium in air

Complete chemical equation 2Mg(s) O2(g) 0 2MgO(s)

Net ionic equation 2Mg(s) O2(g) 0 2Mg2 2O2 (ions in crystal)

When magnesium reacts with oxygen as illustrated in Figure 20-1 each mag-nesium atom transfers two electrons to each oxygen atom What is the resultof this electron transfer The two magnesium atoms become Mg2 ions andthe two oxygen atoms become O2 ions (oxide ions) If you compare this reac-tion with the reaction of sodium and chlorine you will see that they are alikein that both involve the transfer of electrons between atoms A reaction in whichelectrons are transferred from one atom to another is called an oxidationndashreduc-tion reaction For simplicity chemists often refer to oxidationndashreduction reac-tions as redox reactions

Now consider the single-replacement reaction in which chlorine in anaqueous solution replaces bromine from an aqueous solution of potassium bro-mide which is shown in Figure 20-2

Complete chemical equation 2KBr(aq) Cl2(aq) 0 2KCl(aq) Br2(aq)

Net ionic equation 2Br(aq) Cl2(aq) 0 Br2(aq) 2Cl(aq)

Note that chlorine ldquostealsrdquo electrons from bromide ions to become chlorideions When the bromide ions lose their extra electrons the two bromine atomsform a covalent bond with each other to produce Br2 molecules The result ofthis reaction the characteristic color of elemental bromine in solution isshown in Figure 20-2 The formation of the covalent bond by sharing of elec-trons also is an oxidationndashreduction reaction

How do oxidation and reduction differ Originally the word oxidationreferred only to reactions in which a substance combined with oxygen such asthe burning of magnesium in air or the burning of natural gas (methane CH4)in air Today oxidation is defined as the loss of electrons from atoms of a sub-stance Look again at the net ionic equation for the reaction of sodium andchlorine Sodium is oxidized because it loses an electron To state this reac-tion more clearly

Na 0 Na e

For oxidation to take place the electrons lost by the substance that is oxi-dized must be accepted by atoms or ions of another substance In other wordsthere must be an accompanying process that involves the gain of electronsReduction is defined as the gain of electrons by atoms of a substanceFollowing our sodium chloride example further the reduction reaction thataccompanies the oxidation of sodium is the reduction of chlorine

Cl2 2e 0 2Cl

Can oxidation occur without reduction By our definitions oxidation andreduction are complementary processes oxidation cannot occur unless reduc-tion also occurs

It is important to recognize and distinguish between oxidation and reduc-tion The following memory aid may help

LEO the lion says GER or for short LEO GER

This phrase will help you remember that Loss of Electrons is Oxidation andGain of Electrons is Reduction

Changes in oxidation number You may recall from previous chaptersthat the oxidation number of an atom in an ionic compound is the numberof electrons lost or gained by the atom when it forms ions For example lookat the following equation for the redox reaction of potassium metal withbromine vapor

Complete chemical equation 2K(s) Br2(g) 0 2KBr(s)

Net ionic equation 2K(s) Br2(g) 0 2K(s) 2Br(s)

Potassium a group 1A element that tends to lose one electron in reactionsbecause of its low electronegativity is assigned an oxidation number of 1On the other hand bromine a group 7A element that tends to gain one elec-tron in reactions because of its high electronegativity is assigned an oxida-tion number of 1 In redox terms you would say that potassium atoms areoxidized from 0 to the 1 state because each loses an electron and bromineatoms are reduced from 0 to the 1 state because each gains an electron Canyou see why the term reduction is used When an atom or ion is reduced thenumerical value of its oxidation number is lowered

Oxidation numbers are tools that scientists use in written chemical equa-tions to help them keep track of the movement of electrons in a redox reac-tion Like some of the other tools you have learned about in chemistryoxidation numbers have a specific notation Oxidation numbers are writtenwith the positive or negative sign before the number (3 2) whereas ioniccharge is written with the sign after the number (3 2)

Oxidation number 3 Ionic charge 3

Oxidizing and Reducing AgentsChemists also describe the potassiumndashbromine reaction in another way bysaying that ldquopotassium is oxidized by brominerdquo This description is usefulbecause it clearly identifies both the substance that is oxidized and the sub-stance that does the oxidizing The substance that oxidizes another substanceby accepting its electrons is called an oxidizing agent This term is anotherway of saying ldquothe substance that is reducedrdquo The substance that reducesanother substance by losing electrons is called a reducing agent A reducingagent supplies electrons to the substance getting reduced (gaining electrons)and is itself oxidized because it loses electrons By this definition the reduc-ing agent in the potassiumndashbromine reaction is potassium the substance thatis oxidized

A common application of redox chemistry is to remove tarnish from metalobjects such as the silver cups in Figure 20-3 The miniLAB belowdescribes this tarnish removal technique Other oxidizing and reducing agentssuch as those shown in Figure 20-4 play significant roles in your daily lifeFor example when you add chlorine bleach to your laundry to whitenclothes you are using an aqueous solution of sodium hypochlorite (NaClO)an oxidizing agent It oxidizes dyes stains and other materials that discolorclothes Hydrogen peroxide (H2O2) can be used as an antiseptic because itoxidizes some of the vital biomolecules of germs or as an agent to lightenhair because it oxidizes the dark pigment of the hair

Cleaning by RedoxApplying Concepts The tarnish on silver is silversulfide which is formed when the silver reactswith sulfide compounds in the environment Inthis miniLAB you will use an oxidationndashreductionreaction to remove the tarnish from silver or a sil-ver-plated object

Materials aluminum foil steel wool small tar-nished silver object 400-mL beaker (or size largeenough to hold the tarnished object) bakingsoda table salt hot plate beaker tongs

Procedure1 Buff a piece of aluminum foil lightly with steel

wool to remove any oxide coating

2 Wrap the tarnished object in the aluminumfoil making sure that the tarnished areamakes firm contact with the foil

3 Place the wrapped object in the beaker andadd sufficient tap water to cover

4 Add about 1 spoonful of baking soda andabout 1 spoonful of table salt

5 Set the beaker and contents on a hot plateand heat until the water is nearly boilingMaintain the heat approximately 15 min untilthe tarnish disappears

Analysis1 Write the equation for the reaction of silver

Redox and ElectronegativityThe chemistry of oxidationndashreduction reactions is not limited to atoms of anelement changing to ions or the reverse Some redox reactions involve changesin molecular substances or polyatomic ions in which atoms are covalentlybonded to other atoms For example the following equation represents theredox reaction used to manufacture ammonia

N2(g) 3H2(g) 0 2NH3(g)

This process involves neither ions nor any obvious transfer of electrons Thereactants and products are all molecular compounds Still it is a redox reactionin which nitrogen is the oxidizing agent and hydrogen is the reducing agent

In situations such as the formation of NH3 where two atoms share elec-trons how is it possible to say that one atom lost electrons and was oxidizedwhile the other atom gained electrons and was reduced The answer isthat you have to know which atom attracts electrons more strongly or in otherwords which atom is more electronegative You might find it helpfulto review the discussion of electronegativity trends in Chapters 6 and 8Table 20-1 gives the specific electronegativities for hydrogen and nitrogen

For the purpose of studying oxidationndashreduction reactions the more elec-tronegative atom (nitrogen) is treated as if it had been reduced by gaining elec-trons from the other atom The less electronegative atom (hydrogen) is treatedas if it had been oxidized by losing electrons

Identify what is oxidized and what is reduced in this reaction Identify theoxidizing agent and the reducing agent

1 Analyze the ProblemYou are given the ions in the reaction Using this information youmust determine the electron transfers that take place Then you canapply the definitions of oxidizing agent and reducing agent toanswer the question

2 Solve for the UnknownIdentify the oxidation process and the reduction process by evaluating the electron transfer In this case aluminum loses threeelectrons and becomes an aluminum ion in the oxidation processThe iron ion accepts the three electrons lost from aluminum in thereduction processAl 0 Al3 3e (loss of e is oxidation)Fe3 3e 0 Fe (gain of e is reduction)Aluminum is oxidized and therefore is the reducing agent Iron isreduced and therefore is the oxidizing agent

3 Evaluate the AnswerIn this process aluminum lost electrons and is oxidized whereas irongained electrons and is reduced The definitions of oxidation andreduction and oxidizing agent and reducing agent apply Note thatthe oxidation number of oxygen is unchanged in this reaction there-fore oxygen is not a key factor in this problem

Determining Oxidation NumbersIn order to understand all kinds of redox reactions you must have a way todetermine the oxidation number of the atoms involved in the reactionChemists use a set of rules to make this determination easier

Rules for determining oxidation numbers1 The oxidation number of an uncombined atom is zero This is true for

elements that exist as polyatomic molecules such as O2 Cl2 H2 N2 S8

2 The oxidation number of a monatomic ion is equal to the charge on theion For example the oxidation number of a Ca2 ion is 2 and theoxidation number of a Br ion is 1

3 The oxidation number of the more electronegative atom in a moleculeor a complex ion is the same as the charge it would have if it were anion In ammonia (NH3) for example nitrogen is more electronegativethan hydrogen meaning that it attracts electrons more strongly thandoes hydrogen So nitrogen is assigned an oxidation number of 3 asif it had gained three electrons to complete an octet In the compoundsilicon tetrachloride (SiCl4) chlorine is more electronegative than sili-con so each chlorine has an oxidation number of 1 as if it had takenan electron from silicon The silicon atom is given an oxidation numberof 4 as if it had lost electrons to the four chlorine atoms

4 The most electronegative element fluorine always has an oxidationnumber of 1 when it is bonded to another element

5 The oxidation number of oxygen in compounds is always 2 except inperoxides such as hydrogen peroxide (H2O2) where it is 1 When it isbonded to fluorine the only element more electronegative than oxygenthe oxidation number of oxygen is 2

6 The oxidation number of hydrogen in most of its compounds is 1 Theexception to this rule occurs when hydrogen is bonded to less elec-tronegative metals to form hydrides such as LiH NaH CaH2 and AlH3In these compounds hydrogenrsquos oxidation number is 1 because itattracts electrons more strongly than does the metal atom

7 The metals of groups 1A and 2A and aluminum in group 3A formcompounds in which the metal atom always has a positive oxidationnumber equal to the number of its valence electrons (1 2 and 3respectively)

8 The sum of the oxidation numbers in a neutral compound is zero Noticehow the oxidation numbers add up to zero in the following examples

(1) (1) 0 (2) 2(1) 0 2(1) (2) 0 (4) 4(1) 0

Many elements other than those specified in the rules above including mostof the transition metals metalloids and nonmetals can be found with differ-ent oxidation numbers in different compounds For example the two coppercompounds and the two chromium compounds shown in Figure 20-5 a and brespectively have different oxidation numbers

Oxidation Number in Redox ReactionsHaving studied oxidation numbers you are now able to relateoxidationndashreduction reactions to changes in oxidation number Look again atthe equation for a reaction that you saw at the beginning of this section thereplacement of bromine in aqueous KBr by Cl2

2KBr(aq) + Cl2(aq) 0 2KCl(aq) + Br2(aq)

To see how oxidation numbers change start by assigning numbers shown inTable 20-2 to all elements in the balanced equation Then review the changesas shown in the accompanying diagram

As you can see the oxidation number of bromine changed from 1 to 0an increase of 1 At the same time the oxidation number of chlorine changedfrom 0 to 1 a decrease of 1 Therefore chlorine is reduced and bromine isoxidized All redox reactions follow the same pattern When an atom is oxi-dized its oxidation number increases When an atom is reduced its oxida-tion number decreases Note that there is no change in the oxidation numberof potassium The potassium ion takes no part in the reaction and is called aspectator ion How would the reaction differ if you used zinc bromide (ZnBr2)instead of potassium bromide

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

Now look at the equation in unbalanced form

Cu(s) H(aq) NO3(aq) 0 Cu2(aq) NO2(g) H2O(l)

You might even see this same reaction expressed in a way that shows onlythe substances that are oxidized and reduced

Cu(s) NO3(aq) 0 Cu2(aq) NO2(g) (in acid solution)

In this case the hydrogen ion and the water molecule are eliminated becauseneither is oxidized nor reduced The only additional information needed is thatthe reaction takes place in acid solution In acid solution hydrogen ions (H+)and water molecules are abundant and free to participate in redox reactionsas either reactants or products Some redox reactions can occur only in basicsolution When you balance equations for these reactions you may addhydroxide ions (OH) and water molecules to either side of the equationBasic solutions have an abundance of OH ions instead of H3O

impossible Net ionic equations can still be balanced though by applying the oxidation-number method as you will see in Example Problem 20-4 The problem-solving LAB below shows how the oxidation-number methodcan be used for a real-world application

Objectivesbull Recognize the interdepend-

ence of oxidation andreduction processes

bull Derive oxidation and reduc-tion half-reactions from aredox equation

bull Balance redox equations bythe half-reaction method

Vocabularyspecieshalf-reaction

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Balancing Redox Equations by Half-ReactionsYou will learn more about the importance of half-reactions when you studyelectrochemistry in Chapter 21 For now however you can learn to use half-reactions to balance a redox equation First look at an unbalanced equationtaken from Table 20-3 to see how to separate a redox equation into half-reac-tions For example the following unbalanced equation represents the reac-tion that occurs when you put an iron nail into a solution of copper(II) sulfateas shown in Figure 20-8 Iron atoms are oxidized as they lose electrons tothe copper(II) ions

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Section 201 Oxidation and Reduction

In Chapter 10 you learned that a chemical reaction can usually be classified asone of five typesmdashsynthesis decomposition combustion single-replacementor double-replacement In this chapter yoursquoll investigate a special characteris-tic of many of these reactionsmdashthe ability of elements to gain or lose electronswhen they react with other elements You experimented with this characteristicwhen you did the DISCOVERY LAB

Electron Transfer and Redox ReactionsOne of the defining characteristics of single-replacement and combustionreactions is that they always involve the transfer of electrons from one atomto another So do many but not all synthesis and decomposition reactionsFor example you studied the synthesis reaction in which sodium and chlo-rine react to form the ionic compound sodium chloride

Net ionic equation 2Na(s) Cl2(g) 0 2Na 2Cl(ions in crystal)

In this reaction an electron from each of two sodium atoms is transferred tothe Cl2 molecule to form two Cl ions An example of a combustion reactionis the burning of magnesium in air

When magnesium reacts with oxygen as illustrated in Figure 20-1 each mag-nesium atom transfers two electrons to each oxygen atom What is the resultof this electron transfer The two magnesium atoms become Mg2 ions andthe two oxygen atoms become O2 ions (oxide ions) If you compare this reac-tion with the reaction of sodium and chlorine you will see that they are alikein that both involve the transfer of electrons between atoms A reaction in whichelectrons are transferred from one atom to another is called an oxidationndashreduc-tion reaction For simplicity chemists often refer to oxidationndashreduction reac-tions as redox reactions

Now consider the single-replacement reaction in which chlorine in anaqueous solution replaces bromine from an aqueous solution of potassium bro-mide which is shown in Figure 20-2

Complete chemical equation 2KBr(aq) Cl2(aq) 0 2KCl(aq) Br2(aq)

Net ionic equation 2Br(aq) Cl2(aq) 0 Br2(aq) 2Cl(aq)

Note that chlorine ldquostealsrdquo electrons from bromide ions to become chlorideions When the bromide ions lose their extra electrons the two bromine atomsform a covalent bond with each other to produce Br2 molecules The result ofthis reaction the characteristic color of elemental bromine in solution isshown in Figure 20-2 The formation of the covalent bond by sharing of elec-trons also is an oxidationndashreduction reaction

How do oxidation and reduction differ Originally the word oxidationreferred only to reactions in which a substance combined with oxygen such asthe burning of magnesium in air or the burning of natural gas (methane CH4)in air Today oxidation is defined as the loss of electrons from atoms of a sub-stance Look again at the net ionic equation for the reaction of sodium andchlorine Sodium is oxidized because it loses an electron To state this reac-tion more clearly

Na 0 Na e

For oxidation to take place the electrons lost by the substance that is oxi-dized must be accepted by atoms or ions of another substance In other wordsthere must be an accompanying process that involves the gain of electronsReduction is defined as the gain of electrons by atoms of a substanceFollowing our sodium chloride example further the reduction reaction thataccompanies the oxidation of sodium is the reduction of chlorine

Cl2 2e 0 2Cl

Can oxidation occur without reduction By our definitions oxidation andreduction are complementary processes oxidation cannot occur unless reduc-tion also occurs

It is important to recognize and distinguish between oxidation and reduc-tion The following memory aid may help

LEO the lion says GER or for short LEO GER

This phrase will help you remember that Loss of Electrons is Oxidation andGain of Electrons is Reduction

Changes in oxidation number You may recall from previous chaptersthat the oxidation number of an atom in an ionic compound is the numberof electrons lost or gained by the atom when it forms ions For example lookat the following equation for the redox reaction of potassium metal withbromine vapor

Complete chemical equation 2K(s) Br2(g) 0 2KBr(s)

Net ionic equation 2K(s) Br2(g) 0 2K(s) 2Br(s)

Potassium a group 1A element that tends to lose one electron in reactionsbecause of its low electronegativity is assigned an oxidation number of 1On the other hand bromine a group 7A element that tends to gain one elec-tron in reactions because of its high electronegativity is assigned an oxida-tion number of 1 In redox terms you would say that potassium atoms areoxidized from 0 to the 1 state because each loses an electron and bromineatoms are reduced from 0 to the 1 state because each gains an electron Canyou see why the term reduction is used When an atom or ion is reduced thenumerical value of its oxidation number is lowered

Oxidation numbers are tools that scientists use in written chemical equa-tions to help them keep track of the movement of electrons in a redox reac-tion Like some of the other tools you have learned about in chemistryoxidation numbers have a specific notation Oxidation numbers are writtenwith the positive or negative sign before the number (3 2) whereas ioniccharge is written with the sign after the number (3 2)

Oxidizing and Reducing AgentsChemists also describe the potassiumndashbromine reaction in another way bysaying that ldquopotassium is oxidized by brominerdquo This description is usefulbecause it clearly identifies both the substance that is oxidized and the sub-stance that does the oxidizing The substance that oxidizes another substanceby accepting its electrons is called an oxidizing agent This term is anotherway of saying ldquothe substance that is reducedrdquo The substance that reducesanother substance by losing electrons is called a reducing agent A reducingagent supplies electrons to the substance getting reduced (gaining electrons)and is itself oxidized because it loses electrons By this definition the reduc-ing agent in the potassiumndashbromine reaction is potassium the substance thatis oxidized

A common application of redox chemistry is to remove tarnish from metalobjects such as the silver cups in Figure 20-3 The miniLAB belowdescribes this tarnish removal technique Other oxidizing and reducing agentssuch as those shown in Figure 20-4 play significant roles in your daily lifeFor example when you add chlorine bleach to your laundry to whitenclothes you are using an aqueous solution of sodium hypochlorite (NaClO)an oxidizing agent It oxidizes dyes stains and other materials that discolorclothes Hydrogen peroxide (H2O2) can be used as an antiseptic because itoxidizes some of the vital biomolecules of germs or as an agent to lightenhair because it oxidizes the dark pigment of the hair

Redox and ElectronegativityThe chemistry of oxidationndashreduction reactions is not limited to atoms of anelement changing to ions or the reverse Some redox reactions involve changesin molecular substances or polyatomic ions in which atoms are covalentlybonded to other atoms For example the following equation represents theredox reaction used to manufacture ammonia

N2(g) 3H2(g) 0 2NH3(g)

This process involves neither ions nor any obvious transfer of electrons Thereactants and products are all molecular compounds Still it is a redox reactionin which nitrogen is the oxidizing agent and hydrogen is the reducing agent

In situations such as the formation of NH3 where two atoms share elec-trons how is it possible to say that one atom lost electrons and was oxidizedwhile the other atom gained electrons and was reduced The answer isthat you have to know which atom attracts electrons more strongly or in otherwords which atom is more electronegative You might find it helpfulto review the discussion of electronegativity trends in Chapters 6 and 8Table 20-1 gives the specific electronegativities for hydrogen and nitrogen

For the purpose of studying oxidationndashreduction reactions the more elec-tronegative atom (nitrogen) is treated as if it had been reduced by gaining elec-trons from the other atom The less electronegative atom (hydrogen) is treatedas if it had been oxidized by losing electrons

Identify what is oxidized and what is reduced in this reaction Identify theoxidizing agent and the reducing agent

1 Analyze the ProblemYou are given the ions in the reaction Using this information youmust determine the electron transfers that take place Then you canapply the definitions of oxidizing agent and reducing agent toanswer the question

2 Solve for the UnknownIdentify the oxidation process and the reduction process by evaluating the electron transfer In this case aluminum loses threeelectrons and becomes an aluminum ion in the oxidation processThe iron ion accepts the three electrons lost from aluminum in thereduction processAl 0 Al3 3e (loss of e is oxidation)Fe3 3e 0 Fe (gain of e is reduction)Aluminum is oxidized and therefore is the reducing agent Iron isreduced and therefore is the oxidizing agent

3 Evaluate the AnswerIn this process aluminum lost electrons and is oxidized whereas irongained electrons and is reduced The definitions of oxidation andreduction and oxidizing agent and reducing agent apply Note thatthe oxidation number of oxygen is unchanged in this reaction there-fore oxygen is not a key factor in this problem

Determining Oxidation NumbersIn order to understand all kinds of redox reactions you must have a way todetermine the oxidation number of the atoms involved in the reactionChemists use a set of rules to make this determination easier

Rules for determining oxidation numbers1 The oxidation number of an uncombined atom is zero This is true for

elements that exist as polyatomic molecules such as O2 Cl2 H2 N2 S8

2 The oxidation number of a monatomic ion is equal to the charge on theion For example the oxidation number of a Ca2 ion is 2 and theoxidation number of a Br ion is 1

3 The oxidation number of the more electronegative atom in a moleculeor a complex ion is the same as the charge it would have if it were anion In ammonia (NH3) for example nitrogen is more electronegativethan hydrogen meaning that it attracts electrons more strongly thandoes hydrogen So nitrogen is assigned an oxidation number of 3 asif it had gained three electrons to complete an octet In the compoundsilicon tetrachloride (SiCl4) chlorine is more electronegative than sili-con so each chlorine has an oxidation number of 1 as if it had takenan electron from silicon The silicon atom is given an oxidation numberof 4 as if it had lost electrons to the four chlorine atoms

4 The most electronegative element fluorine always has an oxidationnumber of 1 when it is bonded to another element

5 The oxidation number of oxygen in compounds is always 2 except inperoxides such as hydrogen peroxide (H2O2) where it is 1 When it isbonded to fluorine the only element more electronegative than oxygenthe oxidation number of oxygen is 2

6 The oxidation number of hydrogen in most of its compounds is 1 Theexception to this rule occurs when hydrogen is bonded to less elec-tronegative metals to form hydrides such as LiH NaH CaH2 and AlH3In these compounds hydrogenrsquos oxidation number is 1 because itattracts electrons more strongly than does the metal atom

7 The metals of groups 1A and 2A and aluminum in group 3A formcompounds in which the metal atom always has a positive oxidationnumber equal to the number of its valence electrons (1 2 and 3respectively)

8 The sum of the oxidation numbers in a neutral compound is zero Noticehow the oxidation numbers add up to zero in the following examples

(1) (1) 0 (2) 2(1) 0 2(1) (2) 0 (4) 4(1) 0

Many elements other than those specified in the rules above including mostof the transition metals metalloids and nonmetals can be found with differ-ent oxidation numbers in different compounds For example the two coppercompounds and the two chromium compounds shown in Figure 20-5 a and brespectively have different oxidation numbers

As you can see the oxidation number of bromine changed from 1 to 0an increase of 1 At the same time the oxidation number of chlorine changedfrom 0 to 1 a decrease of 1 Therefore chlorine is reduced and bromine isoxidized All redox reactions follow the same pattern When an atom is oxi-dized its oxidation number increases When an atom is reduced its oxida-tion number decreases Note that there is no change in the oxidation numberof potassium The potassium ion takes no part in the reaction and is called aspectator ion How would the reaction differ if you used zinc bromide (ZnBr2)instead of potassium bromide

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

Now look at the equation in unbalanced form

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

5

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

When magnesium reacts with oxygen as illustrated in Figure 20-1 each mag-nesium atom transfers two electrons to each oxygen atom What is the resultof this electron transfer The two magnesium atoms become Mg2 ions andthe two oxygen atoms become O2 ions (oxide ions) If you compare this reac-tion with the reaction of sodium and chlorine you will see that they are alikein that both involve the transfer of electrons between atoms A reaction in whichelectrons are transferred from one atom to another is called an oxidationndashreduc-tion reaction For simplicity chemists often refer to oxidationndashreduction reac-tions as redox reactions

Now consider the single-replacement reaction in which chlorine in anaqueous solution replaces bromine from an aqueous solution of potassium bro-mide which is shown in Figure 20-2

Net ionic equation 2Br(aq) Cl2(aq) 0 Br2(aq) 2Cl(aq)

Note that chlorine ldquostealsrdquo electrons from bromide ions to become chlorideions When the bromide ions lose their extra electrons the two bromine atomsform a covalent bond with each other to produce Br2 molecules The result ofthis reaction the characteristic color of elemental bromine in solution isshown in Figure 20-2 The formation of the covalent bond by sharing of elec-trons also is an oxidationndashreduction reaction

How do oxidation and reduction differ Originally the word oxidationreferred only to reactions in which a substance combined with oxygen such asthe burning of magnesium in air or the burning of natural gas (methane CH4)in air Today oxidation is defined as the loss of electrons from atoms of a sub-stance Look again at the net ionic equation for the reaction of sodium andchlorine Sodium is oxidized because it loses an electron To state this reac-tion more clearly

Na 0 Na e

For oxidation to take place the electrons lost by the substance that is oxi-dized must be accepted by atoms or ions of another substance In other wordsthere must be an accompanying process that involves the gain of electronsReduction is defined as the gain of electrons by atoms of a substanceFollowing our sodium chloride example further the reduction reaction thataccompanies the oxidation of sodium is the reduction of chlorine

Cl2 2e 0 2Cl

Can oxidation occur without reduction By our definitions oxidation andreduction are complementary processes oxidation cannot occur unless reduc-tion also occurs

It is important to recognize and distinguish between oxidation and reduc-tion The following memory aid may help

LEO the lion says GER or for short LEO GER

This phrase will help you remember that Loss of Electrons is Oxidation andGain of Electrons is Reduction

Changes in oxidation number You may recall from previous chaptersthat the oxidation number of an atom in an ionic compound is the numberof electrons lost or gained by the atom when it forms ions For example lookat the following equation for the redox reaction of potassium metal withbromine vapor

Complete chemical equation 2K(s) Br2(g) 0 2KBr(s)

Net ionic equation 2K(s) Br2(g) 0 2K(s) 2Br(s)

Potassium a group 1A element that tends to lose one electron in reactionsbecause of its low electronegativity is assigned an oxidation number of 1On the other hand bromine a group 7A element that tends to gain one elec-tron in reactions because of its high electronegativity is assigned an oxida-tion number of 1 In redox terms you would say that potassium atoms areoxidized from 0 to the 1 state because each loses an electron and bromineatoms are reduced from 0 to the 1 state because each gains an electron Canyou see why the term reduction is used When an atom or ion is reduced thenumerical value of its oxidation number is lowered

Oxidation numbers are tools that scientists use in written chemical equa-tions to help them keep track of the movement of electrons in a redox reac-tion Like some of the other tools you have learned about in chemistryoxidation numbers have a specific notation Oxidation numbers are writtenwith the positive or negative sign before the number (3 2) whereas ioniccharge is written with the sign after the number (3 2)

Oxidizing and Reducing AgentsChemists also describe the potassiumndashbromine reaction in another way bysaying that ldquopotassium is oxidized by brominerdquo This description is usefulbecause it clearly identifies both the substance that is oxidized and the sub-stance that does the oxidizing The substance that oxidizes another substanceby accepting its electrons is called an oxidizing agent This term is anotherway of saying ldquothe substance that is reducedrdquo The substance that reducesanother substance by losing electrons is called a reducing agent A reducingagent supplies electrons to the substance getting reduced (gaining electrons)and is itself oxidized because it loses electrons By this definition the reduc-ing agent in the potassiumndashbromine reaction is potassium the substance thatis oxidized

A common application of redox chemistry is to remove tarnish from metalobjects such as the silver cups in Figure 20-3 The miniLAB belowdescribes this tarnish removal technique Other oxidizing and reducing agentssuch as those shown in Figure 20-4 play significant roles in your daily lifeFor example when you add chlorine bleach to your laundry to whitenclothes you are using an aqueous solution of sodium hypochlorite (NaClO)an oxidizing agent It oxidizes dyes stains and other materials that discolorclothes Hydrogen peroxide (H2O2) can be used as an antiseptic because itoxidizes some of the vital biomolecules of germs or as an agent to lightenhair because it oxidizes the dark pigment of the hair

Redox and ElectronegativityThe chemistry of oxidationndashreduction reactions is not limited to atoms of anelement changing to ions or the reverse Some redox reactions involve changesin molecular substances or polyatomic ions in which atoms are covalentlybonded to other atoms For example the following equation represents theredox reaction used to manufacture ammonia

N2(g) 3H2(g) 0 2NH3(g)

This process involves neither ions nor any obvious transfer of electrons Thereactants and products are all molecular compounds Still it is a redox reactionin which nitrogen is the oxidizing agent and hydrogen is the reducing agent

In situations such as the formation of NH3 where two atoms share elec-trons how is it possible to say that one atom lost electrons and was oxidizedwhile the other atom gained electrons and was reduced The answer isthat you have to know which atom attracts electrons more strongly or in otherwords which atom is more electronegative You might find it helpfulto review the discussion of electronegativity trends in Chapters 6 and 8Table 20-1 gives the specific electronegativities for hydrogen and nitrogen

For the purpose of studying oxidationndashreduction reactions the more elec-tronegative atom (nitrogen) is treated as if it had been reduced by gaining elec-trons from the other atom The less electronegative atom (hydrogen) is treatedas if it had been oxidized by losing electrons

Identify what is oxidized and what is reduced in this reaction Identify theoxidizing agent and the reducing agent

1 Analyze the ProblemYou are given the ions in the reaction Using this information youmust determine the electron transfers that take place Then you canapply the definitions of oxidizing agent and reducing agent toanswer the question

2 Solve for the UnknownIdentify the oxidation process and the reduction process by evaluating the electron transfer In this case aluminum loses threeelectrons and becomes an aluminum ion in the oxidation processThe iron ion accepts the three electrons lost from aluminum in thereduction processAl 0 Al3 3e (loss of e is oxidation)Fe3 3e 0 Fe (gain of e is reduction)Aluminum is oxidized and therefore is the reducing agent Iron isreduced and therefore is the oxidizing agent

3 Evaluate the AnswerIn this process aluminum lost electrons and is oxidized whereas irongained electrons and is reduced The definitions of oxidation andreduction and oxidizing agent and reducing agent apply Note thatthe oxidation number of oxygen is unchanged in this reaction there-fore oxygen is not a key factor in this problem

Determining Oxidation NumbersIn order to understand all kinds of redox reactions you must have a way todetermine the oxidation number of the atoms involved in the reactionChemists use a set of rules to make this determination easier

Rules for determining oxidation numbers1 The oxidation number of an uncombined atom is zero This is true for

elements that exist as polyatomic molecules such as O2 Cl2 H2 N2 S8

2 The oxidation number of a monatomic ion is equal to the charge on theion For example the oxidation number of a Ca2 ion is 2 and theoxidation number of a Br ion is 1

3 The oxidation number of the more electronegative atom in a moleculeor a complex ion is the same as the charge it would have if it were anion In ammonia (NH3) for example nitrogen is more electronegativethan hydrogen meaning that it attracts electrons more strongly thandoes hydrogen So nitrogen is assigned an oxidation number of 3 asif it had gained three electrons to complete an octet In the compoundsilicon tetrachloride (SiCl4) chlorine is more electronegative than sili-con so each chlorine has an oxidation number of 1 as if it had takenan electron from silicon The silicon atom is given an oxidation numberof 4 as if it had lost electrons to the four chlorine atoms

4 The most electronegative element fluorine always has an oxidationnumber of 1 when it is bonded to another element

5 The oxidation number of oxygen in compounds is always 2 except inperoxides such as hydrogen peroxide (H2O2) where it is 1 When it isbonded to fluorine the only element more electronegative than oxygenthe oxidation number of oxygen is 2

6 The oxidation number of hydrogen in most of its compounds is 1 Theexception to this rule occurs when hydrogen is bonded to less elec-tronegative metals to form hydrides such as LiH NaH CaH2 and AlH3In these compounds hydrogenrsquos oxidation number is 1 because itattracts electrons more strongly than does the metal atom

7 The metals of groups 1A and 2A and aluminum in group 3A formcompounds in which the metal atom always has a positive oxidationnumber equal to the number of its valence electrons (1 2 and 3respectively)

8 The sum of the oxidation numbers in a neutral compound is zero Noticehow the oxidation numbers add up to zero in the following examples

(1) (1) 0 (2) 2(1) 0 2(1) (2) 0 (4) 4(1) 0

Many elements other than those specified in the rules above including mostof the transition metals metalloids and nonmetals can be found with differ-ent oxidation numbers in different compounds For example the two coppercompounds and the two chromium compounds shown in Figure 20-5 a and brespectively have different oxidation numbers

Oxidation Number in Redox ReactionsHaving studied oxidation numbers you are now able to relateoxidationndashreduction reactions to changes in oxidation number Look again atthe equation for a reaction that you saw at the beginning of this section thereplacement of bromine in aqueous KBr by Cl2

2KBr(aq) + Cl2(aq) 0 2KCl(aq) + Br2(aq)

To see how oxidation numbers change start by assigning numbers shown inTable 20-2 to all elements in the balanced equation Then review the changesas shown in the accompanying diagram

As you can see the oxidation number of bromine changed from 1 to 0an increase of 1 At the same time the oxidation number of chlorine changedfrom 0 to 1 a decrease of 1 Therefore chlorine is reduced and bromine isoxidized All redox reactions follow the same pattern When an atom is oxi-dized its oxidation number increases When an atom is reduced its oxida-tion number decreases Note that there is no change in the oxidation numberof potassium The potassium ion takes no part in the reaction and is called aspectator ion How would the reaction differ if you used zinc bromide (ZnBr2)instead of potassium bromide

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

How do oxidation and reduction differ Originally the word oxidationreferred only to reactions in which a substance combined with oxygen such asthe burning of magnesium in air or the burning of natural gas (methane CH4)in air Today oxidation is defined as the loss of electrons from atoms of a sub-stance Look again at the net ionic equation for the reaction of sodium andchlorine Sodium is oxidized because it loses an electron To state this reac-tion more clearly

Na 0 Na e

For oxidation to take place the electrons lost by the substance that is oxi-dized must be accepted by atoms or ions of another substance In other wordsthere must be an accompanying process that involves the gain of electronsReduction is defined as the gain of electrons by atoms of a substanceFollowing our sodium chloride example further the reduction reaction thataccompanies the oxidation of sodium is the reduction of chlorine

Cl2 2e 0 2Cl

Can oxidation occur without reduction By our definitions oxidation andreduction are complementary processes oxidation cannot occur unless reduc-tion also occurs

It is important to recognize and distinguish between oxidation and reduc-tion The following memory aid may help

LEO the lion says GER or for short LEO GER

This phrase will help you remember that Loss of Electrons is Oxidation andGain of Electrons is Reduction

Changes in oxidation number You may recall from previous chaptersthat the oxidation number of an atom in an ionic compound is the numberof electrons lost or gained by the atom when it forms ions For example lookat the following equation for the redox reaction of potassium metal withbromine vapor

Complete chemical equation 2K(s) Br2(g) 0 2KBr(s)

Net ionic equation 2K(s) Br2(g) 0 2K(s) 2Br(s)

Potassium a group 1A element that tends to lose one electron in reactionsbecause of its low electronegativity is assigned an oxidation number of 1On the other hand bromine a group 7A element that tends to gain one elec-tron in reactions because of its high electronegativity is assigned an oxida-tion number of 1 In redox terms you would say that potassium atoms areoxidized from 0 to the 1 state because each loses an electron and bromineatoms are reduced from 0 to the 1 state because each gains an electron Canyou see why the term reduction is used When an atom or ion is reduced thenumerical value of its oxidation number is lowered

Oxidation numbers are tools that scientists use in written chemical equa-tions to help them keep track of the movement of electrons in a redox reac-tion Like some of the other tools you have learned about in chemistryoxidation numbers have a specific notation Oxidation numbers are writtenwith the positive or negative sign before the number (3 2) whereas ioniccharge is written with the sign after the number (3 2)

Oxidizing and Reducing AgentsChemists also describe the potassiumndashbromine reaction in another way bysaying that ldquopotassium is oxidized by brominerdquo This description is usefulbecause it clearly identifies both the substance that is oxidized and the sub-stance that does the oxidizing The substance that oxidizes another substanceby accepting its electrons is called an oxidizing agent This term is anotherway of saying ldquothe substance that is reducedrdquo The substance that reducesanother substance by losing electrons is called a reducing agent A reducingagent supplies electrons to the substance getting reduced (gaining electrons)and is itself oxidized because it loses electrons By this definition the reduc-ing agent in the potassiumndashbromine reaction is potassium the substance thatis oxidized

Cleaning by RedoxApplying Concepts The tarnish on silver is silversulfide which is formed when the silver reactswith sulfide compounds in the environment Inthis miniLAB you will use an oxidationndashreductionreaction to remove the tarnish from silver or a sil-ver-plated object

Materials aluminum foil steel wool small tar-nished silver object 400-mL beaker (or size largeenough to hold the tarnished object) bakingsoda table salt hot plate beaker tongs

Procedure1 Buff a piece of aluminum foil lightly with steel

wool to remove any oxide coating

2 Wrap the tarnished object in the aluminumfoil making sure that the tarnished areamakes firm contact with the foil

3 Place the wrapped object in the beaker andadd sufficient tap water to cover

4 Add about 1 spoonful of baking soda andabout 1 spoonful of table salt

5 Set the beaker and contents on a hot plateand heat until the water is nearly boilingMaintain the heat approximately 15 min untilthe tarnish disappears

Analysis1 Write the equation for the reaction of silver

with hydrogen sulfide yielding silver sulfideand hydrogen

2 Write the equation for the reaction of the tar-nish (silver sulfide) with the aluminum foilyielding aluminum sulfide and silver

3 Which metal aluminum or silver is more reac-tive How do you know this from your results

4 Why should you not use an aluminum pan toclean silver objects by this method

Redox and ElectronegativityThe chemistry of oxidationndashreduction reactions is not limited to atoms of anelement changing to ions or the reverse Some redox reactions involve changesin molecular substances or polyatomic ions in which atoms are covalentlybonded to other atoms For example the following equation represents theredox reaction used to manufacture ammonia

N2(g) 3H2(g) 0 2NH3(g)

This process involves neither ions nor any obvious transfer of electrons Thereactants and products are all molecular compounds Still it is a redox reactionin which nitrogen is the oxidizing agent and hydrogen is the reducing agent

In situations such as the formation of NH3 where two atoms share elec-trons how is it possible to say that one atom lost electrons and was oxidizedwhile the other atom gained electrons and was reduced The answer isthat you have to know which atom attracts electrons more strongly or in otherwords which atom is more electronegative You might find it helpfulto review the discussion of electronegativity trends in Chapters 6 and 8Table 20-1 gives the specific electronegativities for hydrogen and nitrogen

For the purpose of studying oxidationndashreduction reactions the more elec-tronegative atom (nitrogen) is treated as if it had been reduced by gaining elec-trons from the other atom The less electronegative atom (hydrogen) is treatedas if it had been oxidized by losing electrons

Identify what is oxidized and what is reduced in this reaction Identify theoxidizing agent and the reducing agent

1 Analyze the ProblemYou are given the ions in the reaction Using this information youmust determine the electron transfers that take place Then you canapply the definitions of oxidizing agent and reducing agent toanswer the question

2 Solve for the UnknownIdentify the oxidation process and the reduction process by evaluating the electron transfer In this case aluminum loses threeelectrons and becomes an aluminum ion in the oxidation processThe iron ion accepts the three electrons lost from aluminum in thereduction processAl 0 Al3 3e (loss of e is oxidation)Fe3 3e 0 Fe (gain of e is reduction)Aluminum is oxidized and therefore is the reducing agent Iron isreduced and therefore is the oxidizing agent

3 Evaluate the AnswerIn this process aluminum lost electrons and is oxidized whereas irongained electrons and is reduced The definitions of oxidation andreduction and oxidizing agent and reducing agent apply Note thatthe oxidation number of oxygen is unchanged in this reaction there-fore oxygen is not a key factor in this problem

Determining Oxidation NumbersIn order to understand all kinds of redox reactions you must have a way todetermine the oxidation number of the atoms involved in the reactionChemists use a set of rules to make this determination easier

Rules for determining oxidation numbers1 The oxidation number of an uncombined atom is zero This is true for

elements that exist as polyatomic molecules such as O2 Cl2 H2 N2 S8

2 The oxidation number of a monatomic ion is equal to the charge on theion For example the oxidation number of a Ca2 ion is 2 and theoxidation number of a Br ion is 1

3 The oxidation number of the more electronegative atom in a moleculeor a complex ion is the same as the charge it would have if it were anion In ammonia (NH3) for example nitrogen is more electronegativethan hydrogen meaning that it attracts electrons more strongly thandoes hydrogen So nitrogen is assigned an oxidation number of 3 asif it had gained three electrons to complete an octet In the compoundsilicon tetrachloride (SiCl4) chlorine is more electronegative than sili-con so each chlorine has an oxidation number of 1 as if it had takenan electron from silicon The silicon atom is given an oxidation numberof 4 as if it had lost electrons to the four chlorine atoms

4 The most electronegative element fluorine always has an oxidationnumber of 1 when it is bonded to another element

5 The oxidation number of oxygen in compounds is always 2 except inperoxides such as hydrogen peroxide (H2O2) where it is 1 When it isbonded to fluorine the only element more electronegative than oxygenthe oxidation number of oxygen is 2

6 The oxidation number of hydrogen in most of its compounds is 1 Theexception to this rule occurs when hydrogen is bonded to less elec-tronegative metals to form hydrides such as LiH NaH CaH2 and AlH3In these compounds hydrogenrsquos oxidation number is 1 because itattracts electrons more strongly than does the metal atom

7 The metals of groups 1A and 2A and aluminum in group 3A formcompounds in which the metal atom always has a positive oxidationnumber equal to the number of its valence electrons (1 2 and 3respectively)

8 The sum of the oxidation numbers in a neutral compound is zero Noticehow the oxidation numbers add up to zero in the following examples

(1) (1) 0 (2) 2(1) 0 2(1) (2) 0 (4) 4(1) 0

NaCl CaBr2 H2S CCl4

9 The sum of the oxidation numbers of the atoms in a polyatomic ion isequal to the charge on the ion The following examples illustrate

(3) 4(1) 1 (4) 3(2) 2

Many elements other than those specified in the rules above including mostof the transition metals metalloids and nonmetals can be found with differ-ent oxidation numbers in different compounds For example the two coppercompounds and the two chromium compounds shown in Figure 20-5 a and brespectively have different oxidation numbers

Oxidation Number in Redox ReactionsHaving studied oxidation numbers you are now able to relateoxidationndashreduction reactions to changes in oxidation number Look again atthe equation for a reaction that you saw at the beginning of this section thereplacement of bromine in aqueous KBr by Cl2

2KBr(aq) + Cl2(aq) 0 2KCl(aq) + Br2(aq)

To see how oxidation numbers change start by assigning numbers shown inTable 20-2 to all elements in the balanced equation Then review the changesas shown in the accompanying diagram

As you can see the oxidation number of bromine changed from 1 to 0an increase of 1 At the same time the oxidation number of chlorine changedfrom 0 to 1 a decrease of 1 Therefore chlorine is reduced and bromine isoxidized All redox reactions follow the same pattern When an atom is oxi-dized its oxidation number increases When an atom is reduced its oxida-tion number decreases Note that there is no change in the oxidation numberof potassium The potassium ion takes no part in the reaction and is called aspectator ion How would the reaction differ if you used zinc bromide (ZnBr2)instead of potassium bromide

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

5

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Oxidizing and Reducing AgentsChemists also describe the potassiumndashbromine reaction in another way bysaying that ldquopotassium is oxidized by brominerdquo This description is usefulbecause it clearly identifies both the substance that is oxidized and the sub-stance that does the oxidizing The substance that oxidizes another substanceby accepting its electrons is called an oxidizing agent This term is anotherway of saying ldquothe substance that is reducedrdquo The substance that reducesanother substance by losing electrons is called a reducing agent A reducingagent supplies electrons to the substance getting reduced (gaining electrons)and is itself oxidized because it loses electrons By this definition the reduc-ing agent in the potassiumndashbromine reaction is potassium the substance thatis oxidized

Cleaning by RedoxApplying Concepts The tarnish on silver is silversulfide which is formed when the silver reactswith sulfide compounds in the environment Inthis miniLAB you will use an oxidationndashreductionreaction to remove the tarnish from silver or a sil-ver-plated object

Materials aluminum foil steel wool small tar-nished silver object 400-mL beaker (or size largeenough to hold the tarnished object) bakingsoda table salt hot plate beaker tongs

Procedure1 Buff a piece of aluminum foil lightly with steel

wool to remove any oxide coating

2 Wrap the tarnished object in the aluminumfoil making sure that the tarnished areamakes firm contact with the foil

3 Place the wrapped object in the beaker andadd sufficient tap water to cover

4 Add about 1 spoonful of baking soda andabout 1 spoonful of table salt

5 Set the beaker and contents on a hot plateand heat until the water is nearly boilingMaintain the heat approximately 15 min untilthe tarnish disappears

Analysis1 Write the equation for the reaction of silver

with hydrogen sulfide yielding silver sulfideand hydrogen

2 Write the equation for the reaction of the tar-nish (silver sulfide) with the aluminum foilyielding aluminum sulfide and silver

3 Which metal aluminum or silver is more reac-tive How do you know this from your results

4 Why should you not use an aluminum pan toclean silver objects by this method

Redox and ElectronegativityThe chemistry of oxidationndashreduction reactions is not limited to atoms of anelement changing to ions or the reverse Some redox reactions involve changesin molecular substances or polyatomic ions in which atoms are covalentlybonded to other atoms For example the following equation represents theredox reaction used to manufacture ammonia

N2(g) 3H2(g) 0 2NH3(g)

This process involves neither ions nor any obvious transfer of electrons Thereactants and products are all molecular compounds Still it is a redox reactionin which nitrogen is the oxidizing agent and hydrogen is the reducing agent

In situations such as the formation of NH3 where two atoms share elec-trons how is it possible to say that one atom lost electrons and was oxidizedwhile the other atom gained electrons and was reduced The answer isthat you have to know which atom attracts electrons more strongly or in otherwords which atom is more electronegative You might find it helpfulto review the discussion of electronegativity trends in Chapters 6 and 8Table 20-1 gives the specific electronegativities for hydrogen and nitrogen

For the purpose of studying oxidationndashreduction reactions the more elec-tronegative atom (nitrogen) is treated as if it had been reduced by gaining elec-trons from the other atom The less electronegative atom (hydrogen) is treatedas if it had been oxidized by losing electrons

Identify what is oxidized and what is reduced in this reaction Identify theoxidizing agent and the reducing agent

1 Analyze the ProblemYou are given the ions in the reaction Using this information youmust determine the electron transfers that take place Then you canapply the definitions of oxidizing agent and reducing agent toanswer the question

2 Solve for the UnknownIdentify the oxidation process and the reduction process by evaluating the electron transfer In this case aluminum loses threeelectrons and becomes an aluminum ion in the oxidation processThe iron ion accepts the three electrons lost from aluminum in thereduction processAl 0 Al3 3e (loss of e is oxidation)Fe3 3e 0 Fe (gain of e is reduction)Aluminum is oxidized and therefore is the reducing agent Iron isreduced and therefore is the oxidizing agent

3 Evaluate the AnswerIn this process aluminum lost electrons and is oxidized whereas irongained electrons and is reduced The definitions of oxidation andreduction and oxidizing agent and reducing agent apply Note thatthe oxidation number of oxygen is unchanged in this reaction there-fore oxygen is not a key factor in this problem

Determining Oxidation NumbersIn order to understand all kinds of redox reactions you must have a way todetermine the oxidation number of the atoms involved in the reactionChemists use a set of rules to make this determination easier

Rules for determining oxidation numbers1 The oxidation number of an uncombined atom is zero This is true for

elements that exist as polyatomic molecules such as O2 Cl2 H2 N2 S8

2 The oxidation number of a monatomic ion is equal to the charge on theion For example the oxidation number of a Ca2 ion is 2 and theoxidation number of a Br ion is 1

3 The oxidation number of the more electronegative atom in a moleculeor a complex ion is the same as the charge it would have if it were anion In ammonia (NH3) for example nitrogen is more electronegativethan hydrogen meaning that it attracts electrons more strongly thandoes hydrogen So nitrogen is assigned an oxidation number of 3 asif it had gained three electrons to complete an octet In the compoundsilicon tetrachloride (SiCl4) chlorine is more electronegative than sili-con so each chlorine has an oxidation number of 1 as if it had takenan electron from silicon The silicon atom is given an oxidation numberof 4 as if it had lost electrons to the four chlorine atoms

4 The most electronegative element fluorine always has an oxidationnumber of 1 when it is bonded to another element

5 The oxidation number of oxygen in compounds is always 2 except inperoxides such as hydrogen peroxide (H2O2) where it is 1 When it isbonded to fluorine the only element more electronegative than oxygenthe oxidation number of oxygen is 2

6 The oxidation number of hydrogen in most of its compounds is 1 Theexception to this rule occurs when hydrogen is bonded to less elec-tronegative metals to form hydrides such as LiH NaH CaH2 and AlH3In these compounds hydrogenrsquos oxidation number is 1 because itattracts electrons more strongly than does the metal atom

7 The metals of groups 1A and 2A and aluminum in group 3A formcompounds in which the metal atom always has a positive oxidationnumber equal to the number of its valence electrons (1 2 and 3respectively)

8 The sum of the oxidation numbers in a neutral compound is zero Noticehow the oxidation numbers add up to zero in the following examples

(1) (1) 0 (2) 2(1) 0 2(1) (2) 0 (4) 4(1) 0

NaCl CaBr2 H2S CCl4

9 The sum of the oxidation numbers of the atoms in a polyatomic ion isequal to the charge on the ion The following examples illustrate

Many elements other than those specified in the rules above including mostof the transition metals metalloids and nonmetals can be found with differ-ent oxidation numbers in different compounds For example the two coppercompounds and the two chromium compounds shown in Figure 20-5 a and brespectively have different oxidation numbers

Oxidation Number in Redox ReactionsHaving studied oxidation numbers you are now able to relateoxidationndashreduction reactions to changes in oxidation number Look again atthe equation for a reaction that you saw at the beginning of this section thereplacement of bromine in aqueous KBr by Cl2

2KBr(aq) + Cl2(aq) 0 2KCl(aq) + Br2(aq)

To see how oxidation numbers change start by assigning numbers shown inTable 20-2 to all elements in the balanced equation Then review the changesas shown in the accompanying diagram

As you can see the oxidation number of bromine changed from 1 to 0an increase of 1 At the same time the oxidation number of chlorine changedfrom 0 to 1 a decrease of 1 Therefore chlorine is reduced and bromine isoxidized All redox reactions follow the same pattern When an atom is oxi-dized its oxidation number increases When an atom is reduced its oxida-tion number decreases Note that there is no change in the oxidation numberof potassium The potassium ion takes no part in the reaction and is called aspectator ion How would the reaction differ if you used zinc bromide (ZnBr2)instead of potassium bromide

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

5

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Redox and ElectronegativityThe chemistry of oxidationndashreduction reactions is not limited to atoms of anelement changing to ions or the reverse Some redox reactions involve changesin molecular substances or polyatomic ions in which atoms are covalentlybonded to other atoms For example the following equation represents theredox reaction used to manufacture ammonia

N2(g) 3H2(g) 0 2NH3(g)

This process involves neither ions nor any obvious transfer of electrons Thereactants and products are all molecular compounds Still it is a redox reactionin which nitrogen is the oxidizing agent and hydrogen is the reducing agent

In situations such as the formation of NH3 where two atoms share elec-trons how is it possible to say that one atom lost electrons and was oxidizedwhile the other atom gained electrons and was reduced The answer isthat you have to know which atom attracts electrons more strongly or in otherwords which atom is more electronegative You might find it helpfulto review the discussion of electronegativity trends in Chapters 6 and 8Table 20-1 gives the specific electronegativities for hydrogen and nitrogen

For the purpose of studying oxidationndashreduction reactions the more elec-tronegative atom (nitrogen) is treated as if it had been reduced by gaining elec-trons from the other atom The less electronegative atom (hydrogen) is treatedas if it had been oxidized by losing electrons

Identify what is oxidized and what is reduced in this reaction Identify theoxidizing agent and the reducing agent

1 Analyze the ProblemYou are given the ions in the reaction Using this information youmust determine the electron transfers that take place Then you canapply the definitions of oxidizing agent and reducing agent toanswer the question

2 Solve for the UnknownIdentify the oxidation process and the reduction process by evaluating the electron transfer In this case aluminum loses threeelectrons and becomes an aluminum ion in the oxidation processThe iron ion accepts the three electrons lost from aluminum in thereduction processAl 0 Al3 3e (loss of e is oxidation)Fe3 3e 0 Fe (gain of e is reduction)Aluminum is oxidized and therefore is the reducing agent Iron isreduced and therefore is the oxidizing agent

3 Evaluate the AnswerIn this process aluminum lost electrons and is oxidized whereas irongained electrons and is reduced The definitions of oxidation andreduction and oxidizing agent and reducing agent apply Note thatthe oxidation number of oxygen is unchanged in this reaction there-fore oxygen is not a key factor in this problem

Determining Oxidation NumbersIn order to understand all kinds of redox reactions you must have a way todetermine the oxidation number of the atoms involved in the reactionChemists use a set of rules to make this determination easier

Rules for determining oxidation numbers1 The oxidation number of an uncombined atom is zero This is true for

elements that exist as polyatomic molecules such as O2 Cl2 H2 N2 S8

2 The oxidation number of a monatomic ion is equal to the charge on theion For example the oxidation number of a Ca2 ion is 2 and theoxidation number of a Br ion is 1

3 The oxidation number of the more electronegative atom in a moleculeor a complex ion is the same as the charge it would have if it were anion In ammonia (NH3) for example nitrogen is more electronegativethan hydrogen meaning that it attracts electrons more strongly thandoes hydrogen So nitrogen is assigned an oxidation number of 3 asif it had gained three electrons to complete an octet In the compoundsilicon tetrachloride (SiCl4) chlorine is more electronegative than sili-con so each chlorine has an oxidation number of 1 as if it had takenan electron from silicon The silicon atom is given an oxidation numberof 4 as if it had lost electrons to the four chlorine atoms

4 The most electronegative element fluorine always has an oxidationnumber of 1 when it is bonded to another element

5 The oxidation number of oxygen in compounds is always 2 except inperoxides such as hydrogen peroxide (H2O2) where it is 1 When it isbonded to fluorine the only element more electronegative than oxygenthe oxidation number of oxygen is 2

6 The oxidation number of hydrogen in most of its compounds is 1 Theexception to this rule occurs when hydrogen is bonded to less elec-tronegative metals to form hydrides such as LiH NaH CaH2 and AlH3In these compounds hydrogenrsquos oxidation number is 1 because itattracts electrons more strongly than does the metal atom

7 The metals of groups 1A and 2A and aluminum in group 3A formcompounds in which the metal atom always has a positive oxidationnumber equal to the number of its valence electrons (1 2 and 3respectively)

8 The sum of the oxidation numbers in a neutral compound is zero Noticehow the oxidation numbers add up to zero in the following examples

(1) (1) 0 (2) 2(1) 0 2(1) (2) 0 (4) 4(1) 0

Many elements other than those specified in the rules above including mostof the transition metals metalloids and nonmetals can be found with differ-ent oxidation numbers in different compounds For example the two coppercompounds and the two chromium compounds shown in Figure 20-5 a and brespectively have different oxidation numbers

Oxidation Number in Redox ReactionsHaving studied oxidation numbers you are now able to relateoxidationndashreduction reactions to changes in oxidation number Look again atthe equation for a reaction that you saw at the beginning of this section thereplacement of bromine in aqueous KBr by Cl2

2KBr(aq) + Cl2(aq) 0 2KCl(aq) + Br2(aq)

To see how oxidation numbers change start by assigning numbers shown inTable 20-2 to all elements in the balanced equation Then review the changesas shown in the accompanying diagram

As you can see the oxidation number of bromine changed from 1 to 0an increase of 1 At the same time the oxidation number of chlorine changedfrom 0 to 1 a decrease of 1 Therefore chlorine is reduced and bromine isoxidized All redox reactions follow the same pattern When an atom is oxi-dized its oxidation number increases When an atom is reduced its oxida-tion number decreases Note that there is no change in the oxidation numberof potassium The potassium ion takes no part in the reaction and is called aspectator ion How would the reaction differ if you used zinc bromide (ZnBr2)instead of potassium bromide

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

Some chemical equations forredox reactions such as thisreaction between copper andnitric acid can be difficult tobalance because one or moreelements may appear severaltimes on both sides of the equa-tion The oxidation-numbermethod makes it easier to bal-ance the equation for this redoxreaction

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

Now look at the equation in unbalanced form

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Balancing Redox Equations by Half-ReactionsYou will learn more about the importance of half-reactions when you studyelectrochemistry in Chapter 21 For now however you can learn to use half-reactions to balance a redox equation First look at an unbalanced equationtaken from Table 20-3 to see how to separate a redox equation into half-reac-tions For example the following unbalanced equation represents the reac-tion that occurs when you put an iron nail into a solution of copper(II) sulfateas shown in Figure 20-8 Iron atoms are oxidized as they lose electrons tothe copper(II) ions

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Identify what is oxidized and what is reduced in this reaction Identify theoxidizing agent and the reducing agent

1 Analyze the ProblemYou are given the ions in the reaction Using this information youmust determine the electron transfers that take place Then you canapply the definitions of oxidizing agent and reducing agent toanswer the question

2 Solve for the UnknownIdentify the oxidation process and the reduction process by evaluating the electron transfer In this case aluminum loses threeelectrons and becomes an aluminum ion in the oxidation processThe iron ion accepts the three electrons lost from aluminum in thereduction processAl 0 Al3 3e (loss of e is oxidation)Fe3 3e 0 Fe (gain of e is reduction)Aluminum is oxidized and therefore is the reducing agent Iron isreduced and therefore is the oxidizing agent

3 Evaluate the AnswerIn this process aluminum lost electrons and is oxidized whereas irongained electrons and is reduced The definitions of oxidation andreduction and oxidizing agent and reducing agent apply Note thatthe oxidation number of oxygen is unchanged in this reaction there-fore oxygen is not a key factor in this problem

Determining Oxidation NumbersIn order to understand all kinds of redox reactions you must have a way todetermine the oxidation number of the atoms involved in the reactionChemists use a set of rules to make this determination easier

Rules for determining oxidation numbers1 The oxidation number of an uncombined atom is zero This is true for

elements that exist as polyatomic molecules such as O2 Cl2 H2 N2 S8

2 The oxidation number of a monatomic ion is equal to the charge on theion For example the oxidation number of a Ca2 ion is 2 and theoxidation number of a Br ion is 1

3 The oxidation number of the more electronegative atom in a moleculeor a complex ion is the same as the charge it would have if it were anion In ammonia (NH3) for example nitrogen is more electronegativethan hydrogen meaning that it attracts electrons more strongly thandoes hydrogen So nitrogen is assigned an oxidation number of 3 asif it had gained three electrons to complete an octet In the compoundsilicon tetrachloride (SiCl4) chlorine is more electronegative than sili-con so each chlorine has an oxidation number of 1 as if it had takenan electron from silicon The silicon atom is given an oxidation numberof 4 as if it had lost electrons to the four chlorine atoms

4 The most electronegative element fluorine always has an oxidationnumber of 1 when it is bonded to another element

5 The oxidation number of oxygen in compounds is always 2 except inperoxides such as hydrogen peroxide (H2O2) where it is 1 When it isbonded to fluorine the only element more electronegative than oxygenthe oxidation number of oxygen is 2

6 The oxidation number of hydrogen in most of its compounds is 1 Theexception to this rule occurs when hydrogen is bonded to less elec-tronegative metals to form hydrides such as LiH NaH CaH2 and AlH3In these compounds hydrogenrsquos oxidation number is 1 because itattracts electrons more strongly than does the metal atom

7 The metals of groups 1A and 2A and aluminum in group 3A formcompounds in which the metal atom always has a positive oxidationnumber equal to the number of its valence electrons (1 2 and 3respectively)

8 The sum of the oxidation numbers in a neutral compound is zero Noticehow the oxidation numbers add up to zero in the following examples

(1) (1) 0 (2) 2(1) 0 2(1) (2) 0 (4) 4(1) 0

NaCl CaBr2 H2S CCl4

9 The sum of the oxidation numbers of the atoms in a polyatomic ion isequal to the charge on the ion The following examples illustrate

(3) 4(1) 1 (4) 3(2) 2

Many elements other than those specified in the rules above including mostof the transition metals metalloids and nonmetals can be found with differ-ent oxidation numbers in different compounds For example the two coppercompounds and the two chromium compounds shown in Figure 20-5 a and brespectively have different oxidation numbers

Oxidation Number in Redox ReactionsHaving studied oxidation numbers you are now able to relateoxidationndashreduction reactions to changes in oxidation number Look again atthe equation for a reaction that you saw at the beginning of this section thereplacement of bromine in aqueous KBr by Cl2

2KBr(aq) + Cl2(aq) 0 2KCl(aq) + Br2(aq)

To see how oxidation numbers change start by assigning numbers shown inTable 20-2 to all elements in the balanced equation Then review the changesas shown in the accompanying diagram

As you can see the oxidation number of bromine changed from 1 to 0an increase of 1 At the same time the oxidation number of chlorine changedfrom 0 to 1 a decrease of 1 Therefore chlorine is reduced and bromine isoxidized All redox reactions follow the same pattern When an atom is oxi-dized its oxidation number increases When an atom is reduced its oxida-tion number decreases Note that there is no change in the oxidation numberof potassium The potassium ion takes no part in the reaction and is called aspectator ion How would the reaction differ if you used zinc bromide (ZnBr2)instead of potassium bromide

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

) ) ) )

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

In this case the hydrogen ion and the water molecule are eliminated becauseneither is oxidized nor reduced The only additional information needed is thatthe reaction takes place in acid solution In acid solution hydrogen ions (H+)and water molecules are abundant and free to participate in redox reactionsas either reactants or products Some redox reactions can occur only in basicsolution When you balance equations for these reactions you may addhydroxide ions (OH) and water molecules to either side of the equationBasic solutions have an abundance of OH ions instead of H3O

Objectivesbull Recognize the interdepend-

ence of oxidation andreduction processes

bull Derive oxidation and reduc-tion half-reactions from aredox equation

bull Balance redox equations bythe half-reaction method

Vocabularyspecieshalf-reaction

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Equations such as these represent half-reactions A half-reaction is one ofthe two parts of a redox reactionmdashthe oxidation half alone or the reductionhalf alone Table 20-3 shows a variety of reduction half-reactions that canaccept electrons from iron oxidizing it from Fe to Fe3

Balancing Redox Equations by Half-ReactionsYou will learn more about the importance of half-reactions when you studyelectrochemistry in Chapter 21 For now however you can learn to use half-reactions to balance a redox equation First look at an unbalanced equationtaken from Table 20-3 to see how to separate a redox equation into half-reac-tions For example the following unbalanced equation represents the reac-tion that occurs when you put an iron nail into a solution of copper(II) sulfateas shown in Figure 20-8 Iron atoms are oxidized as they lose electrons tothe copper(II) ions

Step 3 Balance the atoms and charges in the half-reactions

a In this case the sulfur atoms are balanced on both sides of theequation and the manganese atoms are balanced on both sides ofthe equation Recall that in acid solution H2O molecules are avail-able in abundance and can be used to balance oxygen atoms inthe half-reactions

SO2 2H2O 0 SO42 2e (oxidation)

Step 4 Adjust the coefficients so that the number of electrons lost inoxidation (2) equals the number of electrons gained in reduction (5)In this case the least common multiple of 2 and 5 is 10 Cross-multi-plying gives the balanced oxidation and reduction half-reactions

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Determining Oxidation NumbersIn order to understand all kinds of redox reactions you must have a way todetermine the oxidation number of the atoms involved in the reactionChemists use a set of rules to make this determination easier

Rules for determining oxidation numbers1 The oxidation number of an uncombined atom is zero This is true for

elements that exist as polyatomic molecules such as O2 Cl2 H2 N2 S8

2 The oxidation number of a monatomic ion is equal to the charge on theion For example the oxidation number of a Ca2 ion is 2 and theoxidation number of a Br ion is 1

3 The oxidation number of the more electronegative atom in a moleculeor a complex ion is the same as the charge it would have if it were anion In ammonia (NH3) for example nitrogen is more electronegativethan hydrogen meaning that it attracts electrons more strongly thandoes hydrogen So nitrogen is assigned an oxidation number of 3 asif it had gained three electrons to complete an octet In the compoundsilicon tetrachloride (SiCl4) chlorine is more electronegative than sili-con so each chlorine has an oxidation number of 1 as if it had takenan electron from silicon The silicon atom is given an oxidation numberof 4 as if it had lost electrons to the four chlorine atoms

4 The most electronegative element fluorine always has an oxidationnumber of 1 when it is bonded to another element

5 The oxidation number of oxygen in compounds is always 2 except inperoxides such as hydrogen peroxide (H2O2) where it is 1 When it isbonded to fluorine the only element more electronegative than oxygenthe oxidation number of oxygen is 2

6 The oxidation number of hydrogen in most of its compounds is 1 Theexception to this rule occurs when hydrogen is bonded to less elec-tronegative metals to form hydrides such as LiH NaH CaH2 and AlH3In these compounds hydrogenrsquos oxidation number is 1 because itattracts electrons more strongly than does the metal atom

7 The metals of groups 1A and 2A and aluminum in group 3A formcompounds in which the metal atom always has a positive oxidationnumber equal to the number of its valence electrons (1 2 and 3respectively)

8 The sum of the oxidation numbers in a neutral compound is zero Noticehow the oxidation numbers add up to zero in the following examples

(1) (1) 0 (2) 2(1) 0 2(1) (2) 0 (4) 4(1) 0

NaCl CaBr2 H2S CCl4

9 The sum of the oxidation numbers of the atoms in a polyatomic ion isequal to the charge on the ion The following examples illustrate

(3) 4(1) 1 (4) 3(2) 2

NH4 SO3

2

Many elements other than those specified in the rules above including mostof the transition metals metalloids and nonmetals can be found with differ-ent oxidation numbers in different compounds For example the two coppercompounds and the two chromium compounds shown in Figure 20-5 a and brespectively have different oxidation numbers

Oxidation Number in Redox ReactionsHaving studied oxidation numbers you are now able to relateoxidationndashreduction reactions to changes in oxidation number Look again atthe equation for a reaction that you saw at the beginning of this section thereplacement of bromine in aqueous KBr by Cl2

2KBr(aq) + Cl2(aq) 0 2KCl(aq) + Br2(aq)

To see how oxidation numbers change start by assigning numbers shown inTable 20-2 to all elements in the balanced equation Then review the changesas shown in the accompanying diagram

As you can see the oxidation number of bromine changed from 1 to 0an increase of 1 At the same time the oxidation number of chlorine changedfrom 0 to 1 a decrease of 1 Therefore chlorine is reduced and bromine isoxidized All redox reactions follow the same pattern When an atom is oxi-dized its oxidation number increases When an atom is reduced its oxida-tion number decreases Note that there is no change in the oxidation numberof potassium The potassium ion takes no part in the reaction and is called aspectator ion How would the reaction differ if you used zinc bromide (ZnBr2)instead of potassium bromide

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

Objectivesbull Recognize the interdepend-

ence of oxidation andreduction processes

bull Derive oxidation and reduc-tion half-reactions from aredox equation

bull Balance redox equations bythe half-reaction method

Vocabularyspecieshalf-reaction

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Equations such as these represent half-reactions A half-reaction is one ofthe two parts of a redox reactionmdashthe oxidation half alone or the reductionhalf alone Table 20-3 shows a variety of reduction half-reactions that canaccept electrons from iron oxidizing it from Fe to Fe3

Balancing Redox Equations by Half-ReactionsYou will learn more about the importance of half-reactions when you studyelectrochemistry in Chapter 21 For now however you can learn to use half-reactions to balance a redox equation First look at an unbalanced equationtaken from Table 20-3 to see how to separate a redox equation into half-reac-tions For example the following unbalanced equation represents the reac-tion that occurs when you put an iron nail into a solution of copper(II) sulfateas shown in Figure 20-8 Iron atoms are oxidized as they lose electrons tothe copper(II) ions

Fe(s) CuSO4(aq) 0 Cu(s) Fe2(SO4)3(aq)

1 Analyze the ProblemYou are given the skeleton equation for the reaction of perman-ganate and sulfur dioxide You also know that the reaction takesplace in an acid solution With this information the rules for deter-mining oxidation numbers and the steps for balancing by half-reac-tions you can write a complete balanced equation

7 2

MnO4 5e 0 Mn2 (reduction)

Step 3 Balance the atoms and charges in the half-reactions

a In this case the sulfur atoms are balanced on both sides of theequation and the manganese atoms are balanced on both sides ofthe equation Recall that in acid solution H2O molecules are avail-able in abundance and can be used to balance oxygen atoms inthe half-reactions

SO2 2H2O 0 SO42 2e (oxidation)

MnO4 5e 0 Mn2 4H2O (reduction)

SO2 2H2O 0 SO42 2e 4H (oxidation)

MnO4 5e 8H 0 Mn2 4H2O (reduction)

Step 4 Adjust the coefficients so that the number of electrons lost inoxidation (2) equals the number of electrons gained in reduction (5)In this case the least common multiple of 2 and 5 is 10 Cross-multi-plying gives the balanced oxidation and reduction half-reactions

5SO2 10H2O 0 5SO42 20H 10e (oxidation)

2MnO4ndash 16H 10e 0 2Mn2 8H2O (reduction)

Finally return spectator ions (K) and restore the state descrip-tions In this case two K ions go with the two MnO4

ndash anions onthe left side of the equation Therefore you can add only two K

ions to the right side which will form K2SO4 The remaining SO42ndash

ions recombine with Mn2 and H to form two molecules ofMnSO4 and H2SO4 respectively

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

PRACTICE PROBLEMS

Determining Oxidation NumbersDetermine the oxidation number of each element in the following com-pounds or ionsa KClO3 (potassium chlorate)b SO3

2 (sulfite ion)

1 Analyze the ProblemFrom the rules for determining oxidation numbers you are given theoxidation number of oxygen (2) and potassium (group 1 metal 1)You are also given the overall charge of the compound or ion Usingthis information and applying the rules you can determine the oxida-tion numbers of chlorine and sulfur

Strategy

Assign the known oxidation numbers to their elements set the sumof all oxidation numbers to zero or to the ion charge and solve forthe unknown oxidation number (Let nelement oxidation number ofthe element in question)

Solution

a Potassium chlorate is a neutral salt so oxidation numbers mustadd up to zero According to rule 5 the oxidation number of oxy-gen in compounds is 2 Rule 7 states that Group 1 metals have a1 oxidation number in compounds

(1) (nCl) 3(2) 0

KClO3

1 nCl (6) 0

nCl 5

b Sulfite ion has a charge of 2 so oxidation numbers must add upto 2 According to rule 5 the oxidation number of oxygen incompounds is 2

(nS) 3(2) 2

SO32

nS (6) 2

nS 4

Oxidation Number in Redox ReactionsHaving studied oxidation numbers you are now able to relateoxidationndashreduction reactions to changes in oxidation number Look again atthe equation for a reaction that you saw at the beginning of this section thereplacement of bromine in aqueous KBr by Cl2

2KBr(aq) + Cl2(aq) 0 2KCl(aq) + Br2(aq)

To see how oxidation numbers change start by assigning numbers shown inTable 20-2 to all elements in the balanced equation Then review the changesas shown in the accompanying diagram

As you can see the oxidation number of bromine changed from 1 to 0an increase of 1 At the same time the oxidation number of chlorine changedfrom 0 to 1 a decrease of 1 Therefore chlorine is reduced and bromine isoxidized All redox reactions follow the same pattern When an atom is oxi-dized its oxidation number increases When an atom is reduced its oxida-tion number decreases Note that there is no change in the oxidation numberof potassium The potassium ion takes no part in the reaction and is called aspectator ion How would the reaction differ if you used zinc bromide (ZnBr2)instead of potassium bromide

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

Some chemical equations forredox reactions such as thisreaction between copper andnitric acid can be difficult tobalance because one or moreelements may appear severaltimes on both sides of the equa-tion The oxidation-numbermethod makes it easier to bal-ance the equation for this redoxreaction

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

Now look at the equation in unbalanced form

Vocabularyspecieshalf-reaction

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

5

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Oxidation Number in Redox ReactionsHaving studied oxidation numbers you are now able to relateoxidationndashreduction reactions to changes in oxidation number Look again atthe equation for a reaction that you saw at the beginning of this section thereplacement of bromine in aqueous KBr by Cl2

2KBr(aq) + Cl2(aq) 0 2KCl(aq) + Br2(aq)

To see how oxidation numbers change start by assigning numbers shown inTable 20-2 to all elements in the balanced equation Then review the changesas shown in the accompanying diagram

As you can see the oxidation number of bromine changed from 1 to 0an increase of 1 At the same time the oxidation number of chlorine changedfrom 0 to 1 a decrease of 1 Therefore chlorine is reduced and bromine isoxidized All redox reactions follow the same pattern When an atom is oxi-dized its oxidation number increases When an atom is reduced its oxida-tion number decreases Note that there is no change in the oxidation numberof potassium The potassium ion takes no part in the reaction and is called aspectator ion How would the reaction differ if you used zinc bromide (ZnBr2)instead of potassium bromide

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

The oxidation-number method is convenient for balancing most redox equa-tions but you will see in the next section that there are occasions when youmust balance the net ionic charge on both sides of the equation in addition tobalancing the atoms

Vocabularyspecieshalf-reaction

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Equations such as these represent half-reactions A half-reaction is one ofthe two parts of a redox reactionmdashthe oxidation half alone or the reductionhalf alone Table 20-3 shows a variety of reduction half-reactions that canaccept electrons from iron oxidizing it from Fe to Fe3

Balancing Redox Equations by Half-ReactionsYou will learn more about the importance of half-reactions when you studyelectrochemistry in Chapter 21 For now however you can learn to use half-reactions to balance a redox equation First look at an unbalanced equationtaken from Table 20-3 to see how to separate a redox equation into half-reac-tions For example the following unbalanced equation represents the reac-tion that occurs when you put an iron nail into a solution of copper(II) sulfateas shown in Figure 20-8 Iron atoms are oxidized as they lose electrons tothe copper(II) ions

Fe(s) CuSO4(aq) 0 Cu(s) Fe2(SO4)3(aq)

) is widely used in the chemistry laboratoryas a strong oxidizing agent Permanganate is usually sold as potassiumsalt KMnO4 When sulfur dioxide gas is bubbled into an acidic solution ofpotassium permanganate it reacts to form sulfate ions Balance theredox equation for this reaction using half-reactionsKMnO4(aq) SO2(g) 0 MnSO4(aq) K2SO4(aq)

1 Analyze the ProblemYou are given the skeleton equation for the reaction of perman-ganate and sulfur dioxide You also know that the reaction takesplace in an acid solution With this information the rules for deter-mining oxidation numbers and the steps for balancing by half-reac-tions you can write a complete balanced equation

2 Solve for the UnknownStep 1 Write the net ionic equation for the reaction You can elimi-nate coefficients spectator ions and state symbols

MnO4 SO2 0 Mn2 SO4

SO2 0 SO42 2e (oxidation)

7 2

MnO4 5e 0 Mn2 (reduction)

Step 3 Balance the atoms and charges in the half-reactions

a In this case the sulfur atoms are balanced on both sides of theequation and the manganese atoms are balanced on both sides ofthe equation Recall that in acid solution H2O molecules are avail-able in abundance and can be used to balance oxygen atoms inthe half-reactions

SO2 2H2O 0 SO42 2e (oxidation)

MnO4 5e 0 Mn2 4H2O (reduction)

b Recall also that in acid solution H ions are readily available andcan be used to balance the charge in the half-reactions

SO2 2H2O 0 SO42 2e 4H (oxidation)

MnO4 5e 8H 0 Mn2 4H2O (reduction)

Step 4 Adjust the coefficients so that the number of electrons lost inoxidation (2) equals the number of electrons gained in reduction (5)In this case the least common multiple of 2 and 5 is 10 Cross-multi-plying gives the balanced oxidation and reduction half-reactions

5SO2 10H2O 0 5SO42 20H 10e (oxidation)

2MnO4ndash 16H 10e 0 2Mn2 8H2O (reduction)

Step 5 Add the balanced half-reactions and simplify by canceling orreducing like terms on both sides of the equation

Finally return spectator ions (K) and restore the state descrip-tions In this case two K ions go with the two MnO4

ndash anions onthe left side of the equation Therefore you can add only two K

ions to the right side which will form K2SO4 The remaining SO42ndash

ions recombine with Mn2 and H to form two molecules ofMnSO4 and H2SO4 respectively

5SO2(g) 2H2O(l) 2KMnO4(aq) 0 K2SO4(aq) 2H2SO4(aq) 2MnSO4(aq)

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Section Balancing Redox Equations

You already know that chemical equations are written to represent chemicalreactions by showing what substances react and what products are formedYou also know that chemical equations must be balanced to show the correctquantities of reactants and products Equations for oxidationndashreduction reac-tions are no different In this section yoursquoll learn a specific method to bal-ance redox equations

The Oxidation-Number MethodMany equations for redox reactions are easy to balance For example try tobalance the following unbalanced equation for the redox reaction that occurswhen potassium chlorate is heated and decomposes to produce potassiumchloride and oxygen gas

Unbalanced equation KClO3(s) 0 KCl(s) O2(g)

Did you get the correct result shown below

Balanced equation 2KClO3(s) 0 2KCl(s) 3O2(g)

Equations for other redox reactions are not as easy to balance Study thefollowing unbalanced equation for the reaction that occurs when copper metalis placed in concentrated nitric acid This reaction is shown in Figure 20-6The brown gas you see is nitrogen dioxide (NO2) produced by the reductionof nitrate ions (NO3

) and the blue solution is the result of the oxidation ofcopper to copper(II) ions

Cu(s) HNO3(aq) 0 Cu(NO3)2(aq) NO2(g) H2O(l)

Note that oxygen appears in only one reactant HNO3 but in all three prod-ucts Nitrogen appears in HNO3 and in two of the products Redox equationssuch as this one in which the same element appears in several reactants andproducts can be hard to balance by the conventional method For this rea-son you need to learn a different balancing technique for redox equations thatis based on the fact that the number of electrons transferred from atoms mustequal the number of electrons accepted by other atoms

As you know when an atom loses electrons its oxidation number increaseswhen an atom gains electrons its oxidation number decreases Therefore thetotal increase in oxidation numbers (oxidation) must equal the total decreasein oxidation numbers (reduction) of the atoms involved in the reaction Thebalancing technique called the oxidation-number method is based on theseprinciples The CHEMLAB at the end of this chapter gives you the oppor-tunity to perform and balance the copperndashnitric acid redox reaction

Steps for balancing redox equationsby the oxidation-number method

1 Assign oxidation numbers to all atoms in the equation

2 Identify the atoms that are oxidized and the atoms that are reduced

3 Determine the change in oxidation number for the atoms that are oxi-dized and for the atoms that are reduced

4 Make the change in oxidation numbers equal in magnitude by adjustingcoefficients in the equation

) ) ) )

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

Objectivesbull Recognize the interdepend-

ence of oxidation andreduction processes

bull Derive oxidation and reduc-tion half-reactions from aredox equation

bull Balance redox equations bythe half-reaction method

Vocabularyspecieshalf-reaction

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Equations such as these represent half-reactions A half-reaction is one ofthe two parts of a redox reactionmdashthe oxidation half alone or the reductionhalf alone Table 20-3 shows a variety of reduction half-reactions that canaccept electrons from iron oxidizing it from Fe to Fe3

Balancing Redox Equations by Half-ReactionsYou will learn more about the importance of half-reactions when you studyelectrochemistry in Chapter 21 For now however you can learn to use half-reactions to balance a redox equation First look at an unbalanced equationtaken from Table 20-3 to see how to separate a redox equation into half-reac-tions For example the following unbalanced equation represents the reac-tion that occurs when you put an iron nail into a solution of copper(II) sulfateas shown in Figure 20-8 Iron atoms are oxidized as they lose electrons tothe copper(II) ions

1 Analyze the ProblemYou are given the skeleton equation for the reaction of perman-ganate and sulfur dioxide You also know that the reaction takesplace in an acid solution With this information the rules for deter-mining oxidation numbers and the steps for balancing by half-reac-tions you can write a complete balanced equation

Step 3 Balance the atoms and charges in the half-reactions

a In this case the sulfur atoms are balanced on both sides of theequation and the manganese atoms are balanced on both sides ofthe equation Recall that in acid solution H2O molecules are avail-able in abundance and can be used to balance oxygen atoms inthe half-reactions

SO2 2H2O 0 SO42 2e (oxidation)

MnO4 5e 0 Mn2 4H2O (reduction)

MnO4 5e 8H 0 Mn2 4H2O (reduction)

Step 4 Adjust the coefficients so that the number of electrons lost inoxidation (2) equals the number of electrons gained in reduction (5)In this case the least common multiple of 2 and 5 is 10 Cross-multi-plying gives the balanced oxidation and reduction half-reactions

Finally return spectator ions (K) and restore the state descrip-tions In this case two K ions go with the two MnO4

ndash anions onthe left side of the equation Therefore you can add only two K

ions to the right side which will form K2SO4 The remaining SO42ndash

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

The oxidation number of copper increases from 0 to 2 as it is oxi-dized in the reaction The oxidation number of nitrogen decreasesfrom 5 to 4 as it is reduced in the formation of NO2 The oxida-tion numbers of hydrogen and oxygen do not change Note that the nitrogen atoms remain unchanged in the nitrate ion (NO3

)which appears on both sides of the equation It is neither oxidizednor reducedStep 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitude byplacing the appropriate coefficients in front of the formulas in theequation Because the oxidation number for nitrogen is 1 you mustadd a coefficient 2 to balance This coefficient applies to HNO3 on theleft and NO2 on the right

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

In this case the hydrogen ion and the water molecule are eliminated becauseneither is oxidized nor reduced The only additional information needed is thatthe reaction takes place in acid solution In acid solution hydrogen ions (H+)and water molecules are abundant and free to participate in redox reactionsas either reactants or products Some redox reactions can occur only in basicsolution When you balance equations for these reactions you may addhydroxide ions (OH) and water molecules to either side of the equationBasic solutions have an abundance of OH ions instead of H3O

Objectivesbull Recognize the interdepend-

bull Derive oxidation and reduc-tion half-reactions from aredox equation

bull Balance redox equations bythe half-reaction method

Vocabularyspecieshalf-reaction

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Balancing Redox Equations by Half-ReactionsYou will learn more about the importance of half-reactions when you studyelectrochemistry in Chapter 21 For now however you can learn to use half-reactions to balance a redox equation First look at an unbalanced equationtaken from Table 20-3 to see how to separate a redox equation into half-reac-tions For example the following unbalanced equation represents the reac-tion that occurs when you put an iron nail into a solution of copper(II) sulfateas shown in Figure 20-8 Iron atoms are oxidized as they lose electrons tothe copper(II) ions

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Balancing Net Ionic Redox EquationsSometimes chemists prefer to express redox reactions in the simplest possi-ble termsmdashas an equation showing only the oxidation and reduction processesand nothing else Look again at the balanced equation for the oxidation ofcopper by nitric acid

Cu(s) 4HNO3(aq) 0 Cu(NO3)2(aq) 2NO2(g) 2H2O(l)

Note that the reaction takes place in aqueous solution so HNO3 which is astrong acid will be ionized Likewise copper(II) nitrate (Cu(NO3)2) will bedissociated into ions Therefore the equation can also be written in ionic form

Cu(s) 4H(aq) 4NO3(aq) 0

Cu2(aq) 2NO3(aq) 2NO2(g) 2H2O(l)

You can see that there are four nitrate ions among the reactants but onlytwo of them undergo change to form two nitrogen dioxide molecules Whatis the role of the other nitrate ions The other two are only spectator ions andcan be eliminated from the equation To simplify things when writing redoxequations in ionic form chemists usually indicate hydrogen ions by H withthe understanding that they exist in hydrated form as hydronium ions (H3O

)The equation can then be rewritten showing only the substances that undergochange

Cu(s) 4H(aq) 2NO3(aq) 0 Cu2(aq) 2NO2(g) 2H2O(l)

Now look at the equation in unbalanced form

In this case the hydrogen ion and the water molecule are eliminated becauseneither is oxidized nor reduced The only additional information needed is thatthe reaction takes place in acid solution In acid solution hydrogen ions (H+)and water molecules are abundant and free to participate in redox reactionsas either reactants or products Some redox reactions can occur only in basicsolution When you balance equations for these reactions you may addhydroxide ions (OH) and water molecules to either side of the equationBasic solutions have an abundance of OH ions instead of H3O

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

5

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Step 3 Balance the atoms and charges in the half-reactions

a In this case the sulfur atoms are balanced on both sides of theequation and the manganese atoms are balanced on both sides ofthe equation Recall that in acid solution H2O molecules are avail-able in abundance and can be used to balance oxygen atoms inthe half-reactions

SO2 2H2O 0 SO42 2e (oxidation)

MnO4 5e 8H 0 Mn2 4H2O (reduction)

Step 4 Adjust the coefficients so that the number of electrons lost inoxidation (2) equals the number of electrons gained in reduction (5)In this case the least common multiple of 2 and 5 is 10 Cross-multi-plying gives the balanced oxidation and reduction half-reactions

Finally return spectator ions (K) and restore the state descrip-tions In this case two K ions go with the two MnO4

ndash anions onthe left side of the equation Therefore you can add only two K

ions to the right side which will form K2SO4 The remaining SO42ndash

ions recombine with Mn2 and H to form two molecules ofMnSO4 and H2SO4 respectively

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

The oxidation number of bromine increases from 1 to 0 as it is oxi-dized The oxidation number of chlorine decreases from 7 to 1 asit is reduced Note that no oxygen atoms appear in the products Thisdeficiency will be fixed shortly

Step 3 Draw a line connecting the atoms involved in oxidation andanother line connecting the atoms involved in reduction Write thenet change in oxidation number above or below each line

Step 4 Make the changes in oxidation number equal in magnitudeby placing the appropriate coefficients in front of the formulas in theequation

Note that 4Br2 represents eight bromine atoms to balance the 8Br

on the left sideStep 5 Add enough hydrogen ions and water molecules to the equa-tion to balance the oxygen atoms on both sides This is the reasonthat you must know the conditions of the reaction

H2O molecules Therefore a total of 8H ions will also be needed toform the four water molecules

3 Evaluate the AnswerReview the balanced equation counting the number of atoms to besure there are equal numbers of each element As with any ionicequation you must also check to see if the net charge on the rightequals the net charge on the left Check to be sure that you did notchange any subscripts in the equation

22 Thinking Critically Explain how changes in oxi-dation number are related to the electrons trans-ferred in a redox reaction How are the changesrelated to the processes of oxidation and reduction

23 Applying Concepts The processes used toremove metals from their ores usually involve areduction process For example mercury may beobtained by roasting the ore mercury(II) sulfidewith calcium oxide to produce mercury metal cal-cium sulfide and calcium sulfate Write and bal-ance the redox equation for this process

The oxidation-number method is convenient for balancing most redox equa-tions but you will see in the next section that there are occasions when youmust balance the net ionic charge on both sides of the equation in addition tobalancing the atoms

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Equations such as these represent half-reactions A half-reaction is one ofthe two parts of a redox reactionmdashthe oxidation half alone or the reductionhalf alone Table 20-3 shows a variety of reduction half-reactions that canaccept electrons from iron oxidizing it from Fe to Fe3

Balancing Redox Equations by Half-ReactionsYou will learn more about the importance of half-reactions when you studyelectrochemistry in Chapter 21 For now however you can learn to use half-reactions to balance a redox equation First look at an unbalanced equationtaken from Table 20-3 to see how to separate a redox equation into half-reac-tions For example the following unbalanced equation represents the reac-tion that occurs when you put an iron nail into a solution of copper(II) sulfateas shown in Figure 20-8 Iron atoms are oxidized as they lose electrons tothe copper(II) ions

) is widely used in the chemistry laboratoryas a strong oxidizing agent Permanganate is usually sold as potassiumsalt KMnO4 When sulfur dioxide gas is bubbled into an acidic solution ofpotassium permanganate it reacts to form sulfate ions Balance theredox equation for this reaction using half-reactionsKMnO4(aq) SO2(g) 0 MnSO4(aq) K2SO4(aq)

1 Analyze the ProblemYou are given the skeleton equation for the reaction of perman-ganate and sulfur dioxide You also know that the reaction takesplace in an acid solution With this information the rules for deter-mining oxidation numbers and the steps for balancing by half-reac-tions you can write a complete balanced equation

2 Solve for the UnknownStep 1 Write the net ionic equation for the reaction You can elimi-nate coefficients spectator ions and state symbols

7 2

MnO4 5e 0 Mn2 (reduction)

Step 3 Balance the atoms and charges in the half-reactions

a In this case the sulfur atoms are balanced on both sides of theequation and the manganese atoms are balanced on both sides ofthe equation Recall that in acid solution H2O molecules are avail-able in abundance and can be used to balance oxygen atoms inthe half-reactions

SO2 2H2O 0 SO42 2e (oxidation)

MnO4 5e 0 Mn2 4H2O (reduction)

b Recall also that in acid solution H ions are readily available andcan be used to balance the charge in the half-reactions

SO2 2H2O 0 SO42 2e 4H (oxidation)

MnO4 5e 8H 0 Mn2 4H2O (reduction)

Step 4 Adjust the coefficients so that the number of electrons lost inoxidation (2) equals the number of electrons gained in reduction (5)In this case the least common multiple of 2 and 5 is 10 Cross-multi-plying gives the balanced oxidation and reduction half-reactions

5SO2 10H2O 0 5SO42 20H 10e (oxidation)

2MnO4ndash 16H 10e 0 2Mn2 8H2O (reduction)

Step 5 Add the balanced half-reactions and simplify by canceling orreducing like terms on both sides of the equation

Finally return spectator ions (K) and restore the state descrip-tions In this case two K ions go with the two MnO4

ndash anions onthe left side of the equation Therefore you can add only two K

ions to the right side which will form K2SO4 The remaining SO42ndash

ions recombine with Mn2 and H to form two molecules ofMnSO4 and H2SO4 respectively

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Equations such as these represent half-reactions A half-reaction is one ofthe two parts of a redox reactionmdashthe oxidation half alone or the reductionhalf alone Table 20-3 shows a variety of reduction half-reactions that canaccept electrons from iron oxidizing it from Fe to Fe3

Balancing Redox Equations by Half-ReactionsYou will learn more about the importance of half-reactions when you studyelectrochemistry in Chapter 21 For now however you can learn to use half-reactions to balance a redox equation First look at an unbalanced equationtaken from Table 20-3 to see how to separate a redox equation into half-reac-tions For example the following unbalanced equation represents the reac-tion that occurs when you put an iron nail into a solution of copper(II) sulfateas shown in Figure 20-8 Iron atoms are oxidized as they lose electrons tothe copper(II) ions

Step 3 Balance the atoms and charges in the half-reactions

a In this case the sulfur atoms are balanced on both sides of theequation and the manganese atoms are balanced on both sides ofthe equation Recall that in acid solution H2O molecules are avail-able in abundance and can be used to balance oxygen atoms inthe half-reactions

SO2 2H2O 0 SO42 2e (oxidation)

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

CHAPTER STUDY GUIDE20

Vocabulary

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Throughout this chapter you have read about oxidationndashreduction reactionsYou know that redox reactions involve the loss and gain of electrons Thusthe ldquopairingrdquo or complementary nature of redox reactions is probably appar-ent to you So letrsquos consider the two halves of redox reactions

Identifying Half-ReactionsAs you know oxidationndashreduction reactions can involve molecules ions freeatoms or combinations of all three To make it easier to discuss redox reac-tions without constantly specifying the kind of particle involved chemists usethe term species In chemistry a species is any kind of chemical unit involvedin a process For example a solution of sugar in water contains two majorspecies In the equilibrium equation NH3 H2O 3 NH4

OH there arefour species the two molecules NH3 and H2O and the two ions NH4

and OHOxidationndashreduction reactions take place whenever a species that can give

up electrons (reducing agent) comes in contact with another species that canaccept them (oxidizing agent) In a sense the species being reduced doesnrsquotldquocarerdquo where the electrons are coming from as long as they are readily avail-able Likewise the species undergoing oxidation doesnrsquot ldquocarerdquo where its elec-trons go as long as a willing receiver is available The cartoon electrondonoracceptor machine shown in Figure 20-7 illustrates this principle

For example active metals can be oxidized by a variety of oxidizingagents When iron rusts it is oxidized by oxygen You can also say that ironreduces oxygen because iron acts as a reducing agent

4Fe 3O2 0 2Fe2O3

But iron can reduce many other oxidizing agents including chlorine

2Fe 3Cl2 0 2FeCl3

In this reaction each iron atom is oxidized by losing three electrons to becomean Fe3 ion This is the oxidation half of the oxidationndashreduction reactionRecall that e represents one electron

Fe 0 Fe3 3e

At the same time each chlorine atom in Cl2 is reduced by accepting one electron to become a Cl ion This is the reduction half of the oxidation-reduction reaction

Cl2 2e 0 2ClFigure 20-7

This imaginary electron machineillustrates the point that theelectrons that are involved inredox reactions can come fromany source as long as they areavailable to transfer It alsopoints out that reduction thecomplimentary process of oxida-tion requires something toaccept the electrons These twoprocesses can be identified andseparated to help understandredox reactions and balanceredox equations

Equations such as these represent half-reactions A half-reaction is one ofthe two parts of a redox reactionmdashthe oxidation half alone or the reductionhalf alone Table 20-3 shows a variety of reduction half-reactions that canaccept electrons from iron oxidizing it from Fe to Fe3

Balancing Redox Equations by Half-ReactionsYou will learn more about the importance of half-reactions when you studyelectrochemistry in Chapter 21 For now however you can learn to use half-reactions to balance a redox equation First look at an unbalanced equationtaken from Table 20-3 to see how to separate a redox equation into half-reac-tions For example the following unbalanced equation represents the reac-tion that occurs when you put an iron nail into a solution of copper(II) sulfateas shown in Figure 20-8 Iron atoms are oxidized as they lose electrons tothe copper(II) ions

7 2

MnO4 5e 0 Mn2 (reduction)

Step 3 Balance the atoms and charges in the half-reactions

a In this case the sulfur atoms are balanced on both sides of theequation and the manganese atoms are balanced on both sides ofthe equation Recall that in acid solution H2O molecules are avail-able in abundance and can be used to balance oxygen atoms inthe half-reactions

SO2 2H2O 0 SO42 2e (oxidation)

MnO4 5e 0 Mn2 4H2O (reduction)

b Recall also that in acid solution H ions are readily available andcan be used to balance the charge in the half-reactions

SO2 2H2O 0 SO42 2e 4H (oxidation)

MnO4 5e 8H 0 Mn2 4H2O (reduction)

Step 4 Adjust the coefficients so that the number of electrons lost inoxidation (2) equals the number of electrons gained in reduction (5)In this case the least common multiple of 2 and 5 is 10 Cross-multi-plying gives the balanced oxidation and reduction half-reactions

5SO2 10H2O 0 5SO42 20H 10e (oxidation)

2MnO4ndash 16H 10e 0 2Mn2 8H2O (reduction)

Finally return spectator ions (K) and restore the state descrip-tions In this case two K ions go with the two MnO4

ndash anions onthe left side of the equation Therefore you can add only two K

ions to the right side which will form K2SO4 The remaining SO42ndash

ions recombine with Mn2 and H to form two molecules ofMnSO4 and H2SO4 respectively

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

5

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

5

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

CHAPTER STUDY GUIDE20

Vocabulary

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

EXAMPLE PROBLEM 20-5

Balancing a Redox Equation by Half-ReactionsThe permanganate ion (MnO4

) is widely used in the chemistry laboratoryas a strong oxidizing agent Permanganate is usually sold as potassiumsalt KMnO4 When sulfur dioxide gas is bubbled into an acidic solution ofpotassium permanganate it reacts to form sulfate ions Balance theredox equation for this reaction using half-reactionsKMnO4(aq) SO2(g) 0 MnSO4(aq) K2SO4(aq)

1 Analyze the ProblemYou are given the skeleton equation for the reaction of perman-ganate and sulfur dioxide You also know that the reaction takesplace in an acid solution With this information the rules for deter-mining oxidation numbers and the steps for balancing by half-reac-tions you can write a complete balanced equation

2 Solve for the UnknownStep 1 Write the net ionic equation for the reaction You can elimi-nate coefficients spectator ions and state symbols

MnO4 SO2 0 Mn2 SO4

2

Step 2 Write the oxidation and reduction half-reactions for the netionic equation including oxidation numbers Recall the rules forassigning oxidation numbers from page 641

4 6

SO2 0 SO42 2e (oxidation)

7 2

MnO4 5e 0 Mn2 (reduction)

Step 3 Balance the atoms and charges in the half-reactions

a In this case the sulfur atoms are balanced on both sides of theequation and the manganese atoms are balanced on both sides ofthe equation Recall that in acid solution H2O molecules are avail-able in abundance and can be used to balance oxygen atoms inthe half-reactions

SO2 2H2O 0 SO42 2e (oxidation)

MnO4 5e 0 Mn2 4H2O (reduction)

b Recall also that in acid solution H ions are readily available andcan be used to balance the charge in the half-reactions

SO2 2H2O 0 SO42 2e 4H (oxidation)

MnO4 5e 8H 0 Mn2 4H2O (reduction)

Step 4 Adjust the coefficients so that the number of electrons lost inoxidation (2) equals the number of electrons gained in reduction (5)In this case the least common multiple of 2 and 5 is 10 Cross-multi-plying gives the balanced oxidation and reduction half-reactions

5SO2 10H2O 0 5SO42 20H 10e (oxidation)

2MnO4ndash 16H 10e 0 2Mn2 8H2O (reduction)

Step 5 Add the balanced half-reactions and simplify by canceling orreducing like terms on both sides of the equation

5SO2 2H2O 2MnO4 0 5SO4

Finally return spectator ions (K) and restore the state descrip-tions In this case two K ions go with the two MnO4

ndash anions onthe left side of the equation Therefore you can add only two K

ions to the right side which will form K2SO4 The remaining SO42ndash

ions recombine with Mn2 and H to form two molecules ofMnSO4 and H2SO4 respectively

5SO2(g) 2H2O(l) 2KMnO4(aq) 0 K2SO4(aq) 2H2SO4(aq) 2MnSO4(aq)

3 Evaluate the AnswerA review of the balanced equation indicates that the number ofatoms of each element is equal on both sides of the equation Nosubscripts have been changed

PRACTICE PROBLEMSUse the half-reaction method to balance the following redox equationsBegin with step 2 of Example Problem 20-5 and leave the balanced equa-tion in ionic form

(aq) Bi2(aq) (in acid solution)

26 N2O(g) ClO(aq) 0 NO2(aq) Cl(aq) (in basic solution) Hint

Add O and H in the form of OH ions and H2O molecules

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

5

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

CHAPTER STUDY GUIDE20

Vocabulary

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Photographicfilm contains small grains of silver bromide(AgBr) suspended in a gelat- inous emulsion that is spread onto a flexible backing material

1

When a camera shutter opens incominglight energizes the silver bromide grains causing some of the bromide ions to lose an electron and reduce some of the silver ions to silver atoms These are called activated grains

2

In a darkroom a reducing chemical suchas hydroquinone or pyrogallol reduces allof the silver ions in any activated AgBr grainto silver atoms (The silver atoms that were created in step 2 act as catalysts in this reduc-tion) The reducing agent does not react with silver ions in AgBr grains that are not activated

3

Now the remaining silver bromide must be removed to keep the film from darkening Sodium thiosulfate reacts with the silver bromide to form bromide ions and a water-soluble complex ion The film is washed to remove the processing chemicals and the soluble reaction products The resulting image is a negative image of the original subject

4

A positive image is created by virtually an identicalseries of reactions after light is shown through thenegative film onto light-sensitive photographicpaper

1 Predicting Time temperature and solutionconcentration are all important factors in thedeveloping process What would be the con-sequence of leaving the film too long in thehydroquinone developer (Hint the developeris a reducing agent)

2 Hypothesizing Color photographs are com-posed of dyes formed during the develop-ment of the silver image The silver metalmust be removed because it is opaque Usethe redox principle to explain how the silvercould be removed from the color photo

Photographic FilmBlack and white photography is a popular art formThe spectacular images that are captured on andprinted from black and white film are the product of aseries of redox reactions The first redox reaction cap-tures the image on the film inside the camera The sec-ond is a reaction to produce a negative image of theexposed film The third redox reaction creates the posi-tive print from the negative film image

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations

Summary201 Oxidation and Reductionbull An oxidationndashreduction (redox) reaction is any

chemical reaction in which electrons are transferredfrom one atom to another Most chemical reactionsother than double replacement reactions are oxida-tionndashreduction reactions

bull Oxidation occurs when an atom loses electronsReduction occurs when an atom gains electrons

bull Oxidation increases an atomrsquos oxidation number andreduction decreases an atomrsquos oxidation number

bull Oxidation and reduction must always occur togetherbecause the reduction process requires a supply ofelectrons available only from the oxidation processAt the same time the oxidation process must have areceiver for lost electrons

bull The species that is oxidized in a redox reaction is thereducing agent and loses electrons The species thatis reduced is the oxidizing agent and gains electrons

bull The oxidation number of an element in a compoundcan be determined by applying a series of rules tothe atoms in the compound

202 Balancing Redox Equationsbull Many simple redox equations may be balanced by

inspection The oxidation-number method can beused to balance more difficult reactions

bull Redox equations are often balanced by examiningthe change in oxidation number that occurs in theoxidized and reduced species The following princi-ple is then applied

e lost in oxidation e gained in reduction

Therefore the total increase in oxidation numbersequals the total decrease in oxidation numbers

bull Redox reactions that take place in acidic solutionoften use water molecules and hydrogen ions in theprocess Redox reactions that take place in basicsolution often use water molecules and hydroxideions in the process Therefore it is appropriate toadd these species to the equation in order to balancethe numbers of oxygen andor hydrogen atoms

bull Redox reactions involving ionic species may be rep-resented by net ionic equations leaving out specta-tor ions

203 Half-Reactionsbull The oxidation and reduction processes of a redox

reaction can be represented as half-reactions

bull An oxidation half-reaction shows the number ofelectrons lost when a species is oxidized A reduc-tion half-reaction shows the number of electronsgained when a species is reduced

bull The fact that an oxidation process must always becoupled with a reduction process provides a basis forusing half-reactions to balance redox equations
