Chemistry - Ionic Equilibrium Question with Solution | TestHub

$\text{HOCl}\stackrel{}{\rightleftharpoons }{\text{H}}^{\text{+}}+{\text{OCl}}^{-}$
$\mathrm{C}\left(1-\mathrm{\alpha }\right)\mathrm{C}\mathrm{\alpha }\mathrm{C}\mathrm{\alpha }$
$\mathrm{k}\mathrm{\alpha }=\mathrm{C}{\mathrm{\alpha }}^2$
${\text{H}}^{\oplus }=\mathrm{C}\mathrm{\alpha }=\sqrt{{\mathrm{k}}_{\mathrm{a}}\times \mathrm{C}}$
$=\sqrt{3.5\times {10}^{-8}\times 0.40}$
$\left[{\text{H}}^{\text{+}}\right]=1.83\times {10}^{-14}$
