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

At $298 \, K$,the equivalent conductivity of a $0.01 \, M$ solution of aniline hydrochloride is $122.5 \, \Omega^{-1} \, cm^2 \, eq^{-1}$,but in the presence of a sufficient excess of aniline to prevent hydrolysis,it is $106.5 \, \Omega^{-1} \, cm^2 \, eq^{-1}$. The equivalent conductivity of $HCl$ at infinite dilution is $426.0 \, \Omega^{-1} \, cm^2 \, eq^{-1}$. The hydrolysis constant of aniline is:

What is the $pH$ of the solution containing $1.342 \times 10^{-3} \ M \ H^{+}$ ions?
$(\log 1.342 = 0.1277)$

$A$ solution whose $pH$ value is less than $7$ will be

If $20 \ mL$ of an acidic solution of $pH$ $3$ is diluted to $100 \ mL$,the $H^{+}$ ion concentration will be

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?
