An acid dissociation constant, Kₐ, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction HA<=>A⁻+H⁺ known as dissociation in the context of acid–base reactions. The chemical species HA is an acid that dissociates into A⁻, the conjugate base of the acid and a hydrogen ion, H⁺.
