ionic strength of solution (u) = 1/2Ci.zi^2
u = 1/2(0.05 x 1^2 + 0.05 x 1^2 + 0.05 x 1^2 + 0.05 x 1^2)
= 0.1
Using extended debye-huckel equation
Activity coefficient [Y] for BrO3-
= inv. log[-0.51 x 1^1 x sq.rt.(0.1)/(1+3.3 x 0.154 x sq.rt.(0.1))]
= 0.726
Activity coefficient [Y] for Pb2+ = 0.370
let x amount of Pb(BrO3)2 is in solution
then,
Ksp = [Pb2+][BrO3-]
2.1 x 10^-6 = (x)(0.370)(2x)^2.(0.726)^2
x = 0.014 M
molar solubility = 0.014 M
