Which one of the following statements is not true?

View answer and explanation

Correct option: C

The pH of

1 \times {10^{ - 8}}\;M\;\mathrm{HCl}

is 8

Option C is correct because the pH of a very dilute strong acid like

1 \times 10^{-8} M \;HCl

cannot be 8. It must be less than 7, considering the contribution of water's autoionization.
