WebIonic product of water: Ionic product of water is defined as the product of molar concentrations of H + and OH-at a specified temperature. The ionization of water can be represented as: H 2 O (l) Water ⇌ H + (aq) Hydrogen ion + OH-(aq) Hydroxide ion. The ionization constant is given as shown below. K = [H +] [OH-] [H 2 O] K [H 2 O] = [H ... WebHowever, as the concentration of the water effectively remains constant on both sides of the equilibrium then the [H 2 O] term can be removed to a very close approximation and the equilibrium constant denoted as Kw (sometimes called the ionic product of water).This gives: Kw = [H +][OH-]. The constant Kw remains unchanged at constant temperature (as … hanging material from ceiling
