The Ksp of nickel(II) hydroxide, Ni(OH)2, is 5.84 × 10-16. Calculate the molar solubility of this compound.

.........Ni(OH)2 ==> Ni^2+ + 2OH^-
I........solid.......0.......0
C.......solid........x.......2x
E.......solid........x.......2x

Ksp = 5.84E-16 = (Ni^2+)(OH^-)
Substitute and solve for x = solubility Ni(OH)2.
