Chemistry - Ionic Equilibrium Question with Solution | TestHub

For a sparingly soluble salt ${\mathrm{AB}}_2$, the equilibrium concentrations of ${\mathrm{A}}^{2+}$ ions and $B^{-}$ions are $1.2\times 10^{-4}\mathrm{M}$ and $0.24\times 10^{-3}\mathrm{M}$, respectively. The solubility product of ${\mathrm{AB}}_2$ is :
