Which of the following is not correct:

\((A)\) \([{ H }^{ + }]=[{ OH }^{ - }]=\sqrt { { K }_{ w } } \) for a neutral solution at all temperatures.

\((B)\) \([{ H }^{ + }]=[{ OH }^{ - }]={ 10 }^{ -7 }\) for a neutral solution at all temperatures.

\((C)\) \([{ H }^{ + }]>\sqrt { { K }_{ w } } \) and \([{ OH }^{ - }]<\sqrt { { K }_{ w } }\) for an acidic solution.

\((D)\) \([{ H }^{ + }]<\sqrt { { K }_{ w } } \) and \([{ OH }^{ - }]>\sqrt { { K }_{ w } } \) for an alkaline soluton.
