Question

The Ksp value for lead sulfide, PbS, is 1.0 x 10^-28. What is the concentration of Pb2 in a saturated solution of lead sulfide?

Answer 1

280

Answer 2

PbS --> Pb+2 & S-2

x rekeases [x] & [x]

Ksp = [Pb+2] [S-2]

1.0 x 10^-28 = [x] [x]

X = 1.0 x 10^-14 molar Pb+2 , S-2,

so your answer is 1.0 x 10^-14 Molar is the concentration of Pb2 in a saturated solution of lead sulfide
