Chemistry - Ionic Equilibrium Question with Solution | TestHub

$\mathrm{p}\mathrm{H}$of${10}^{–8}\mathrm{ }\left(\mathrm{M}\right)\mathrm{ }\mathrm{H}\mathrm{C}\mathrm{l}$will be lesser than 7 as it is acidic solution.
$\left[{\text{H}}^{+}\right]={\left[{\text{H}}^{+}\right]}_{\text{HCl}}+{\left[{\text{H}}^{+}\right]}_{{\text{H}}_{\text{2}}\text{O}}$
$\left[{\text{H}}^{+}\right]={10}^{-8}+{10}^{-7}$
$\therefore \left[{\text{H}}^{\text{+}}\right]=1.1\times {10}^{-7}$
$\text{pH}\text{=}\text{6}\text{.96}$
