Suppose 0.010 M sodium sulfide (NaS2) is added to the solution above (in #7) containing nickel nitrate (NiNO3) and ammonia (NH3). Would you expect nickel(II) sulfide (NiS) to precipitate? The Ksp of nickel(II) sulfide is 3.0 x10–19, and its molecular weight is 122.81 g/mol. The Kf of Ni(NH3)6+2 is 5.6 x108. You can assume no other reactions occur.
