Chemistry 9.4 Naming and Writing Formulas for Acids and Bases

AcidA compound that contains one or more hydrogen atoms and produced hydrogen (H⁺) ions when dissolved in water.
BaseA base is an ionic compound that produces hydroxide ions when dissolved in water.
What are the 3 rules for naming acids?1. When the name of the anion ends in -ide, the acid name begins with the prefix hydro-. The stem of the anion has the suffix -ic and is followed by the word acid.

2. When the anion ends in -ite, the acid name is the stem of the anion with the suffix of -ous, followed by the word acid.

3.When the anion name ends in -ate, the acid name is the stem of the anion with the suffix -ic followed by the word acid.
