Answer. Ionic product constant (Kw) of water is product of equilibrium constant (Kc) and molar concentration of water [H2O]. Such as;
Kc [H2O] = [H+] [OH-]
Or
Kw = [H+] [OH-]
As this equation shows ionic- product of water is product of H+ and OH- ions. More is
concentration of ions. More will be the ionic product. As we know ionization depends upon temperature it increases with increasing of temperature. Therefore, ionic product constant also increases with increasing of temperature and vice versa
