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. WebDetermine the dominant acid-base equilibrium that results when each of the following pairs of solutions is mixed. Indicate the equilibrium by writing 1 for a strong acid, 3 for a weak acid, 4 for an acidic buffer, 7 for a neutral solution, 10 for a basic buffer, 11 for a weak base, and 13 for a strong base.
