The ionic product of water, often denoted as Kw, is a fundamental concept in electro-analytical chemistry and is a key parameter in various chemical and biochemical processes. It represents the equilibrium constant for the autoionization of water, which is the self-ionization of water molecules into hydronium ions (H3O+) and hydroxide ions (OH-):

H2O(l) ⇌ H3O+(aq) + OH-(aq)

Kw is defined as the product of the concentrations of H3O+ and OH- ions at a given temperature:

Kw = [H3O+][OH-]
