Question
There are conventions for naming and constructing the formulas for acids and bases just as there are for other types of compounds. There are three main rules for naming acids, as shown in the table. For example, an acid that contains a hydrogen ion and an acetate anion is called acetic acid. Type of acid Naming convention Hydrogen ion Nonmetal anion Prefix hydro Change nonmetal ending to ic acid Hydrogen ion Polyatomic ion ending in ate No prefix Change polyatomic ion ending to ic acid Hydrogen ion Polyatomic ion ending in ite No prefix Change polyatomic ion ending to ous acid There is one main rule shown in the table for naming bases. For example, a base that contains a sodium ion and a hydroxide ion is called sodium hydroxide. Type of base Naming convention Metal ion Hydroxide ion Metal name followed by hydroxide
