... dissociation: HA + H2O <===> H3O+ + AThe acid dissociation constant, Ka, is a measure of the how much the acid dissociates. Ka = [H30+][A-]/[HA] Similarly, a weak monovalent base, BOH, dissociates to give B+ and OH-. The base dissociation constant, Kb, is a measure of the degree that the base dissoc ...

Determination of K of Weak Acids
... The ionization constant of a weak acid can be determined experimentally by measuring the H3O concentration in a dilute aqueous solution of the weak acid. This procedure is most accurate when the solution contains equal molar amounts of the weak acid and its conjugate base. Consider acetic acid as an ...
