This is known as the self-ionization of water. Using the concentrations of ions produced, it is possible to determine the equilibrium constant for the ionization of water, also known as the ion product constant of water.
WebThe equilibrium constant for the ionization of water, Kw, is called the ion-product of water. In pure water at 25 °C, Kw has a value of 1.0 × 10−14. The dissociation of water gives one H3O+ ion and one OH− ion and thus their concentrations are equal.
