Chemistry - Ionic Equilibrium Question with Solution | TestHub

Calculate the molarity of $\mathrm{HOCl}(\mathrm{aq})$ solution($K_a\left(HOCl\right)=2\times 10^{-6}$ ) that can be added in a 0.1 M aqueous solution of ${\mathrm{CH}}_3\mathrm{COOH}$ without changing degree of dissociation of ${\mathrm{CH}}_3\mathrm{COOH}$.

Given : $K_a\left(C{H}_{3}COOH\right)=10^{-5}$.
