$pH$ of $10^{-8} \ M$ $Ba(OH)_2$ solution will be

$0.001 \ mol$ of a strong electrolyte $M(OH)_2$ is dissolved to make $20 \ mL$ of a saturated solution. Calculate its $pH$ $(K_w = 1 \times 10^{-14})$.

Calculate the $pH$ of $1.36 \times 10^{-2} \ M$ solution of perchloric acid.

$100 \ mL$ of $0.1 \ M$ $HCl$ is taken in a beaker and to it $100 \ mL$ of $0.1 \ M$ $NaOH$ is added in steps of $2 \ mL$ and the $pH$ is continuously measured. Which of the following graphs correctly depicts the change in $pH$?

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