WebMay 25, 2024 · The acid dissociation constant is the equilibrium constant of the dissociation reaction of an acid and is denoted by K a. This equilibrium constant is a quantitative measure of the strength of an acid in a solution. K a is commonly expressed in units of mol/L. There are tables of acid dissociation constants, for easy reference. WebKa is the acid dissociation constant. It is used to determine how much an acid dissociates in solution. The larger the Ka, the higher would be dissociation. Hence stronger would be the acid. pKa is related to Ka as, pKa = – log[Ka] Table of Content.
