In qualitative analysis, the metals of Group I can be separated from other ion 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 xx 10^(-10), K_(sp)` fr `PbCl_(2) = 1.7 xx 10^(-5)`)A. `[Ag^(+)] = 1.8 xx 10^(-9) M, [Pb^(2+)] = 1.7 xx 10^(-3)M`B. `[Ag^(+)] = 1.8 xx 10^(-11) M, [Pb^(2+)] = 1.7 xx 10^(-4)M`C. `[Ag^(+)] = 1.8 xx 10^(-7) M, [Pb^(2+)] = 1.7 xx 10^(-6)M`D. `[Ag^(+)] = 1.8 xx 10^(-11) M, [Pb^(2+)] = 1.7 xx 10^(-5)M` |
