(Acids and Salts)

Bell RingerFriday, 12-3-10

Using your Periodic Table and your ion charts, name the ionic chemical

compounds:

NaClAlBr3HClH2SO4

AnnouncementsWe will have a test

next Tuesday.The remediation for

TEKSCheck #2 is now available, but you

must come to me to get clearance to take

it.

AcidsAn acid is a distinct type of compound.

Most acids used in the laboratory can

be classified as either:

binary acids

oxyacids

AcidsBinary acids are acids that consist of two

elements, usually hydrogen and one of the halogens - fluorine, chlorine, bromine, or

iodine.

HClHFHBrHI

AcidsOxyacids are acids that contain hydrogen,

oxygen, and a third element (usually a nonmetal).

HNO3 H2SO4

H3PO4

AcidsAcids were first recognized as a specific class of compounds based on their properties in

solutions of water.Consequently, in chemical

nomenclature, the term acid usually refers to a solution in water of one of these special compounds rather than to the

compound itself.For example, hydrochloric acid

refers to a water solution of the molecular compound hydrogen chloride, HCl.

Acids

Naming AcidsNaming binary acids:

Example: HFhydro + fluor + ic

Example: HClhydro + chlor + ic

Example: HBrhydro + brom + ic

Example: HIhydro + iod+ ic

Naming AcidsNaming oxyacids:Example: HNO3

nitr + ic Example: H2SO4

sulfur + icExample: H3PO4phosphor + ic

SaltsA salt is an ionic

compound composed of a cation from a base and the anion from an acid.

For example, table salt (NaCl) contains the anion

from hydrochloric acid (HCl) and the cation from

the base sodium hydroxide (NaOH.)

HCl NaOH+ - + -

Salts are named in the same way as other ionic compounds.
