Naming Acids

Binary acids : acids that are made of only two elements.

Anion end in –ide. A. Prefix is always hydro B. Name the second element

with the suffix; -ic acid Example: HCl is Hydrochloric acid

Naming Acids continued

polyatomic anions. Anion ends in –ite

- A. acid ends in –ous acid- Example: H2SO3 is Sulfurous

acid

Naming Acids concluded

polyatomic anions. Anion ends in –ate

- A. acid ends in –ic acid- Example: H2SO4 is Sulfuric acid

Naming Bases

To name a base, use the ionic compound nomenclature.

Example: KOH, NaOHPotassium hydroxide

and sodium hydroxide

Safety in the Lab

Do what you oughter,

Add acid to water.

Safety continued.

Adding water to acid will cause it to heat and splatter.

This will damage skin and eyes.

Wash with water and soap!!

Safety Continued

Due to the slippery nature of bases,

They are more dangerous to your eyes than acid!!

Wear your goggles!!
