Question

The Ksp of PbBr2 is 6.60x10^-6

What is the molar solubility of PbBr2 in pure water?

What is the molar solubility of PbBr2 in 0.500M KBr solution?

What is the molar solubility of PbBr2 in a 0.500M Pb(NO3)2 solution?

Explanation / Answer

A. PbBr2 ---> Pb2+ + 2Br- Ksp = 6.60 x 10^-6 Ksp = [Pb2+][Br-]^2 6.60 x 10^-6 = (x)(2x)^2 6.60 x 10^-6 = 4x^3 1.65 x 10^-6 = x^3 0.0118 M = x B. PbBr2 ---> Pb2+ + 2Br- Ksp = 6.60 x 10^-6 Ksp = [Pb2+][Br-]^2 6.60 x 10^-6 = (x)(0.500)^2 6.60 x 10^-6 = 0.25x 2.64 x 10^-5 M = x C. PbBr2 ---> Pb2+ + 2Br- Ksp = 6.60 x 10^-6 Ksp = [Pb2+][Br-]^2 6.60 x 10^-6 = (0.500)(2x)^2 6.60 x 10^-6 = (0.500)(4x^2) 6.60 x 10^-6 = 2x^2 3.3 x 10^-6 = x^2 0.00182 M = x
