answer

-ate anions make -ic acids, -ite anions make -ous acids
question

Naming Bases
answer

Covalent bases are usually amines-Derivatives of ammonia, A hydrogen ion can attach to a lone pair of electrons, naming is based on the number of groups attached to N, Ionic bases follow the same naming rule as other ionic compounds
