Precipitation: Ksp vs Q
18. Aqueous Equilibrium / Precipitation: Ksp vs Q / Problem 3
A 0.25 M HNO3 solution contains 0.020 M Zn2+ and 0.020 M Ni2+. Can bubbling H2S through the solution separate Zn2+ from Ni2+? The [H2S] in a saturated solution of H2S is approximately 0.10 M. (Kspa ZnS = 1.7 × 10−2, Kspa NiS = 3.2)
