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

What will be the $pH$ of a $10^{-8} \ M \ HCl$ 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 hydroxyl ion concentration of $10^{-2} \ M \ HCl$ is:

The $pH$ value of a $\frac{N}{10} \ NaOH$ solution is:

Weight of $Ca(OH)_2$ needed to prepare $250 \ mL$ of solution with $pH = 13$. (in $g$)
