# Which of these is NOT true?

## A) Strongly basic solutions have larger $\left[{\text{H}}^{+}\right]$ than pure water does. B) Strongly acidic solutions have larger $\left[{\text{H}}^{+}\right]$ than pure water does. C) Strongly acidic solutions have smaller $\left[{\text{OH}}^{-}\right]$ than pure water does. D) Strongly basic solutions have larger $\left[{\text{OH}}^{-}\right]$ than pure water does.

Strong Bases don't have ${\text{H}}^{+}$concentration larger than from water, or they donate no ${\text{H}}^{+}$ ions. But this is applicable to typical strong acids, and not bases. Therefore $A$ is the correct choice.
