The $pH$ value of $0.1 \, M \, HCl$ is approximately $1$. What will be the approximate $pH$ value of $0.05 \, M \, H_2SO_4$?

How many liters of water must be added to $1 \ L$ of an aqueous $HCl$ solution with $pH = 1$ to make the $pH$ of the resulting solution equal to $2$ (in $L$)?

$200 \ mL$ of an aqueous solution of $HCl$ $(pH=2)$ is mixed with $300 \ mL$ of aqueous solution of $NaOH$ $(pH=12)$ and is diluted to $1.0 \ L$. The $pH$ of the resulting solution is

The $pH$ of $100 \ mL$ of an aqueous solution of a strong acid is $1$. The volume of water to be added to change its $pH$ to $2$ is .......... $mL$.

What is the concentration of hydrogen $[H^{+}]$ ions in $0.01 \, M \, HCl$?

The $pH$ of a $10^{-3} \ M$ solution of hydrochloric acid will be:
