...........AB2 ==> A^2+ + 2B^-
I..........solid...0.......0
C..........solid...s.......2s
E..........solid...s.......2s
Ksp = (A^2+)(B^-)^2
Ksp = (S)(2S)^2
Ksp = 4S^3
I..........solid...0.......0
C..........solid...s.......2s
E..........solid...s.......2s
Ksp = (A^2+)(B^-)^2
Ksp = (S)(2S)^2
Ksp = 4S^3
