Water ionizes by the equation h2o(l)βh+(aq)+ohβ(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [ohβ]: kw=[h+][ohβ] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.
