NAMING ACIDS

Three rules can help you name an acid with the general formula H n X. The naming system depends on the name of the anion. Each of the rules deals with an anion with a different suffix: -ide, -ite, and -ate. 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. EXAMPLES HCl(aq) is named hydrochloric acid. H 2 S(aq) is named hydrosulfuric acid.

2.When the anion name ends in -ite, the acid name is the stem of the anion with the suffix -ous, followed by the word acid. EXAMPLES H 2 SO 3 (aq) is named sulfurous 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. EXAMPLES HNO 3 (aq) is named nitric acid.
