Heavy water is less dissociated than light water at given temperature, and the true concentration of D ions is less than  H ions would be for a light water sample at the same temperature. The same is true of OD vs.  OH ions. For heavy water Kw D2O (25.0 °C) = 1.35 × 10 , and [D  ] must equal [OD  ] for neutral water. Thus pKw D2O = p[OD ] + p[D ] = 7.44 + 7.44 = 14.87 (25.0 °C), and the p[D ] of neutral heavy wat…
