Question
what is the molar solubility of Fe(OH)3 in a buffered solution with pH=8.2 at 25 degrees Celsius given ksp =4.0*10^-38.

........Fe(OH)3 ==> Fe^3+ + 3OH^-
I........solid.......0.......0
C........solid.......x.......3x
E........solid.......x.......3x
Ksp = (Fe^3+)(OH^-)^3
You know Ksp, OH can be calculated from pH, solve for x which is the solubility.
