Acids are compounds that produce hydrogen ions (H+) when dissolved in water.
Binary acids contain hydrogen and a nonmetal. They are named with the prefix hydro- and the suffix -ic acid.
- Example: HCl(aq) is hydrochloric acid
Oxyacids contain hydrogen, a nonmetal, and oxygen. The naming depends on the oxidation state of the nonmetal.
- -ite suffix indicates the nonmetal has a lower oxidation state
- -ate suffix indicates the nonmetal has a higher oxidation state
- Example: H₂SO₃(aq) is sulfurous acid, while H₂SO₄(aq) is sulfuric acid
Hypo prefix indicates the nonmetal has the lowest oxidation state
- Example: HBrO(aq) is hypobromous acid
Per prefix indicates the nonmetal has the highest oxidation state
- Example: HClO₄(aq) is perchloric acid
