The $pH$ of $10^{-7} \ N \ HCl$ is

An analyst wants to convert $1 \ L$ of $HCl$ solution with $pH = 1$ to a solution of $HCl$ with $pH = 2$. The volume of water needed to do this dilution is $...... \ mL$. (Nearest Integer)

Calculate the volume of $0.1 \ M \ NaOH$ required to complete the neutralization of $300 \ mL$ of $HCl$ solution having $pH = 2.25$. (in $mL$)

The $pH$ of an aqueous solution containing $[H^{+}] = 3 \times 10^{-3} \ M$ is

What is the $pH$ of a solution containing $4.62 \times 10^{-4} \ M \ H^{+}$ ions?
