Nomenclature - Purdue University

For example, hydrogen chloride (HCl) dissolves in water to form hydrochloric acid; hydrogen bromide (HBr) forms hydrobromic acid; and hydrogen cyanide (HCN) forms hydrocyanic acid. Many of the oxygen-rich polyatomic negative ions in Table 2.1 form acids that are named by replacing the suffix - ate with -ic and the suffix -ite with -ous .
