Naming of Acids

As you learned, acids are defined by both the Arrhenius definition and the Bronsted-Lowry definition. An acid is a molecular compound that contains one or more hydrogen atoms. When dissolved in water, the chemical bond between the hydrogen atom and the rest of the molecule breaks. This produces a hydrogen ion and anion.

There are also different types of acids. Binary acids consist of hydrogen and one other element. Oxoacids consist of hydrogen, oxygen, and a third element. Usually this third element is a nonmetal. A third type of acid is the organic acids. Organic acids are composed of an organic compound with some acidic properties.

The naming of acids is based on the anion. Anions are either monatomic or polyatomic. All monatomic ions end with –ide. Polyatomic ions end in either –ate or –ite. In this activity, click the check boxes from the clipboard to examine the three rules used for naming an acid.

Writing Formulas for Acids

Acids are neutral compounds. The charge of the anion has to balance out the charge of the H+ ions. Since H+ ions carry a single positive charge, the number of H+ ions in the formula is equal to the quantity of the negative charge of the anion. In hydrochloric acid (HCl), there is one positive hydrogen ion. This is balanced out by one negative chloride ion. In sulfuric acid, H2SO4, there are two hydrogen atoms that are balanced out by the negative two charge of the sulfate ion.
