Vedclass · Answer

(B) Electrical conductivity in a liquid requires the presence of mobile ions.Pure water is a very weak electrolyte and undergoes self-ionization to a negligible extent,represented by the equation: $2H_2O(l) \rightleftharpoons H_3O^+(aq) + OH^-(aq)$.Because the concentration of these ions is extremely low ($10^{-7} \ M$ at $298 \ K$),pure water is considered a non-conductor of electricity.
