Question

Consider the two equilibria:
ZnS(s) ⇌ Zn2+(aq) + S2−(aq)                                          Ksp = 1 × 10−27
2H2 O(l) + H2 S(aq) ⇌ 2H3 O+(aq) + S2−(aq)                         K = 1.0 × 10−26
and calculate the concentration of hydronium ion required to prevent the precipitation of ZnS in a solution that is 0.050 M in Zn2+ and saturated with H2S (0.10 M H2S).
