Webacid, any substance that in water solution tastes sour, changes the colour of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions (acid catalysis). Examples of acids include the inorganic substances known as the mineral … WebApr 21, 2024 · Students should understand there are several different theories of acids and bases (ie, the Arrhenius, Brønsted–Lowry and Lewis theories). Strong acids/bases are fully dissociated in aqueous solutions, while weak acids/bases are only partially dissociated. K a is the acid dissociation constant. Acids and bases form conjugate acid–base pairs.
