WebK w = water autoionization constant=1.0 x 10 -14 @ 25 °C From the chemical equation just above, it can be seen that H 3 O + and OH¯ concentrations are in the molar ratio of one-to-one. This means that [H 3 O +] = [OH¯]. Therefore the values of [H 3 O +] and [OH¯] can be determined by taking the square root of K w.
