The $pOH$ of beer is $10.0$. What is the concentration of hydrogen ions $[H^+]$?

The value of the ion product constant for water,$(K_w)$ at $60\,^{\circ}C$ is $9.6 \times 10^{-14} \,M^2$. What are the $[H_3O^{+}]$ of a neutral aqueous solution at $60\,^{\circ}C$ and the nature of an aqueous solution with a $pH = 7.0$ at $60\,^{\circ}C$,respectively?

Identify the incorrect statement.

$A$ is an aqueous acid; $B$ is an aqueous base. They are diluted separately,then:

In a solution of acid,the $H^{+}$ concentration is $10^{-10} \ M$. The $pH$ of this solution will be:

The $pH$ of a solution having $[OH^{-}] = 10^{-7} \ M$ is
