Solution:
A) PbBr2 is dissociated as,
PbBr2 = Pb2+ + 2Br-
Ksp = S x (2S)^2
Ksp = 4S^3
Ksp = 4 x (0.0118)^3 = 6.57 x 10^-6
B) Molarity of 8.90 x 10^-6 g Y2(CO3)3 is calculated as,
M = (8.90 x 10^-6 g / 357.84 g mol-1) x 0.1 L
M = 2.49 x 10^-7 M
Ksp for Y2(CO3)3 is calculated as,
Y2(CO3)3 = 2Y^3+ + 3CO3^2-
Ksp = (2S)^2 x (3S)^3
Ksp = 108 S^5
Ksp = 108 x (2.49 x 10^-7)^5
Ksp = 1.03 x 10^-31
C) Ag2CrO4 is dissociated as,
Ag2CrO4 = 2Ag+ + CrO4^2-
Ksp =( 2S )^2 x S
Ksp = 4S^3
5.40 x 10^-12 = 4S^3
S^3 = 1.35 x 10^-12
S = 1.11 x 10^-4 M
Solubility = 1.1 x 10^-4 mol/L
