Acids and Salts in oxidation
Acids participate in processes that result in the formation of salts. In these reactions, metal ions or ammonium ions take the place of the acid's hydrogen ions. Acids and many metals, although not all, interact. As the metals combine with the acid to produce salts, hydrogen gas is created. In the introduction to the study of acids, this class experiment is frequently used to demonstrate that this behavior is a typical attribute.
