18. Aqueous Equilibrium / Precipitation: Ksp vs Q / Problem 13
A solution is created by mixing 0.20 M Ni(CH3COO)2, 0.30 M HNO3 and 0.20 M H2S.
(i) Will NiS precipitate out of the solution? (Kspa NiS = 3.2)
(ii) If the pH of the solution is increased to 7 using a phosphate buffer, will NiS precipitate out of the solution?
