diketahui Ksp PbSO4 adalah 3x10 pangkat - 5 tentukan kelarutan PbSO4 dalam air dan larutan PbL2 0,05M

*Dalam air :
PbSO4 = Pb^2+ + SO4^2-
Ksp = [Pb^2+] + [SO4^2-]
Ksp = s × s
Ksp = s^2
3×10^-5 = s^2
s = 5 × 10^-3

*Dalam PbL2 0.05M :
PbL2 = Pb^2+ + 2L^-
Ksp = [Pb^2+] + [L^-]
0.05M 0.1
PbSO4 = Pb^2+ + SO4^2-
Ksp = [Pb^2+] + [SO4^2-]
3×10^-5 = 0.05 × [SO4^2-]
[SO4^2-] = 6×10^-4
kelarutan = 1/1 × 6×10^-4
