Autoprotolysis

Autoprotolysis

Transfer of a hydrogen ion between molecules of the same substance, e.g. the autoprotolysis of methanol (2 CH₃OH = CH₃OH₂⁺ + CH₃O^-). Autoprotolysis of water into hydronium ions and hydroxide ions results in equilibrium concentrations that satisfy Kw = (H3O+)(OH-), where the autoprotolysis constant Kw is equal to 1.01 × 10-14 at 25°C.
