WebPure water has pH = 7. That means the [H +1] = 1.0 x 10 -7 M Because you get one OH -1 for each H +1 the [OH -1] = 1.0 x 10 -7 M Therefore Kw = [H +1 ] [OH -1] = 1.0 x 10 -14 M By adding acids to water you are actually disturbing the equilibrium. As more H +1 ions are dissolved the equilibrium shifts left and consumes hydroxide ions.
