Most acids used in the laboratory are either binary acids or oxyacids. Binary acids are acids that consist of two elements, usually hydrogen and a halogen. Oxyacids are acids that contain hydrogen, oxygen, and a third element (usually a nonmetal). Section 1 Chemical Names and Formulas

ResourcesChapter menu Chapter 7 Acids and Salts, continued In the laboratory, the term acid usually refers to a solution in water of an acid compound rather than the acid itself. Section 1 Chemical Names and Formulas example: hydrochloric acid refers to a water solution of the molecular compound hydrogen chloride, HCl Many polyatomic ions are produced by the loss of hydrogen ions from oxyacids. examples: sulfuric acidH 2 SO 4 sulfate nitric acidHNO 3 nitrate phosphoric acidH 3 PO 4 phosphate

Calcium sulfate, CaSO 4, is a salt containing the anion from sulfuric acid, H 2 SO 4. The bicarbonate ion,, comes from carbonic acid, H 2 CO 3. Section 1 Chemical Names and Formulas
