$\mathrm{H}_2 \mathrm{~S}$ is passed into one $\mathrm{nm}^3$ of a solution containing 0.1 mole of $\mathrm{Zn}^{2+}$ and 0.01 mole of $\mathrm{Cu}^{2+}$ till the sulphide ion concentration reaches to $8.1 \times 10^{-19}$ moles. Which one of the following statements is true?
$\left[\mathrm{K}_{\mathrm{sp}}\right.$ of $\mathrm{ZnS}$ and $\mathrm{CuS}$ are $3 \times 10^{-22}$ and $8 \times 10^{-36}$ respectively.]
