Given that the dissociation constant for $H_2O$ is $K_w = 1 \times 10^{-14} \ mol^2 \ L^{-2}$,what is the $pH$ of a $0.001 \ M \ KOH$ solution?

What is the $pH$ of a $NaOH$ solution with a concentration of $0.01 \ g \ L^{-1}$?

If $4.0 \, g$ of $NaOH$ is present in $1 \, L$ of solution,then its $pH$ will be:

When an aqueous solution of a strong acid with $pH = 5$ is mixed with an equal volume of an aqueous solution of a strong acid with $pH = 3$,what will be the $pH$ of the resulting solution?

What is the normality of an aqueous solution of $H_2SO_4$ having $pH = 1$ (in $N$)?

When $50 \, mL$ of $0.4 \, N$ $HCl$ and $50 \, mL$ of $0.2 \, N$ $NaOH$ solutions are mixed,the $pH$ of the resulting solution will be ........
