Chemistry - Ionic Equilibrium Question with Solution | TestHub

A saturated solution of ${\mathrm{H}}_2\mathrm{S}$ in $0.1\mathrm{M}\mathrm{HCl}$ at $25^{\circ }\mathrm{C}$ contains ${\mathrm{S}}^{2-}$ ion concentration of $10^{-23}\mathrm{mol}{\mathrm{L}}^{-1}$. The solubility product of some sulphides are $\mathrm{CuS}=10^{-44},\mathrm{FeS}=10^{-14},\mathrm{MnS}=10^{-15},\mathrm{CdS}=$ $10^{-25}$. If $0.01\mathrm{M}$ solution of these salts in $1\mathrm{M}$ $\mathrm{HCl}$ are saturated with ${\mathrm{H}}_2\mathrm{S}$, which of these will be precipitated?
