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

When equal volumes of solutions with $pH = 6$ and $pH = 3$ are mixed,what is the $pH$ of the resulting solution?

Given $pH$ of a solution $A$ is $3$ and it is mixed with another solution $B$ having $pH$ $2$. If both are mixed in equal volumes,then the resultant $pH$ of the solution will be

The $pH$ of $0.0001 \ N$ solution of $KOH$ will be

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 a $0.001 \, M$ solution of $HCl$ is:
