........Fe(OH)3 ==> Fe^3+ + 3OH^-
I.......solid........0........0
C.......solid........x........3x
E.......solid........x........3x
Ksp = (F^3+)(OH^-)^3
Substitute the E line into Ksp expression and solve for x, = [Fe(OH)3] in mols/L. That x molar mass = grams.
The Ksp of iron(II) hydroxide, Fe(OH)2, is 4.87 × 10-17. Calculate the solubility of this compound in g/L.
