Chemistry - Ionic Equilibrium Question with Solution | TestHub

A solution which is$10^{-3}$M each in$\mathrm{M}{\mathrm{n}}^{2+},\mathrm{F}{\mathrm{e}}^{2+},\mathrm{Z}{\mathrm{n}}^{2+}$and$\mathrm{H}{\mathrm{g}}^{2+}$is treated with$10^{-16}$M sulphide ion. If${\mathrm{K}}_{\mathrm{s}\mathrm{p}}$of$\mathrm{M}\mathrm{n}\mathrm{S}$, FeS, ZnS and HgS are$10^{-13},10^{-18},10^{-24}$and$10^{-53}$respectively. Which one will precipitate first?
