.................Ni(OH)2 ==> Ni^2+ + 2OH^-
I................solid..................0.............0
C...............solid..................x.............2x
E................solid..................x.............2x
Ksp = (Ni^2+)(OH^-)^2
You know Ksp. You can calculate OH^- from pH. Solve for (Ni^2+) which is the solubility. Post your work if you get stuck.
