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
