From the given concentration of OH - ion in aqueous solution at 100 ° C , the concentration of H 3 O + has to be calculated. Concept Introduction: Autoionization of water is the reaction in which the water undergoes ionization to give a proton and a hydroxide ion. Water is a very weak electrolyte and hence it does not completely dissociate into the ions. The ionization happens to a very less extent only. The ionization of water is an equilibrium reaction and hence this has equilibrium rate constant. K w = [ H 3 O + ] [ OH − ] = 1.0 × 10 − 14 To calculate the concentration of H 3 O +
