Question
What is the concentration of Pb+2 when PbSO4 (Ksp = 1.8 × 10-8) begins to precipitate from a solution that is 0.0045 M in SO4-2 ?
Options
A.4 × 10-8 M
B.1 × 10-6 M
C.2 × 10-8 M
D.4 × 10-6 M
Solution
Ksp = [Pb+2] [SO4-2]
1.8 × 10-8 = [Pb+2] (0.0045)
Pb+2 = 4 × 10-6
1.8 × 10-8 = [Pb+2] (0.0045)
Pb+2 = 4 × 10-6
