In qualitative analysis, the metals of group $I$ can be separated from other ions by precipitating them as chloride salts. A solution initially contains $Ag^+$ and $Pb^{2+}$ at a concentration of $0.10 \,M.$ Aqueous $HCl$ is added to this solution until the $Cl^-$ concentration is $0.10\, M.$What will the concentrations of $Ag^+$ and $Pb^{2+}$ be at equilibrium ? ($K_{sp}$ for $AgCl = 1.8 \times 10^{-10},$$ K_{sp}$ for $PbCl_2 = 1.7 \times 10^{-5}$)
