Question
Zinc sulfide, ZnS, is sparingly soluble in most situations. With ammonia, Zn2+ forms four complexes, Zn(NH3)2+, Zn(NH3)22+, Zn(NH3)32+, and Zn(NH3)42+. Ammonia is, of course, a
Zinc sulfide, ZnS, is sparingly soluble in most situations. With ammonia, Zn2+ forms four complexes, Zn(NH3)2+, Zn(NH3)22+, Zn(NH3)32+, and Zn(NH3)42+. Ammonia is, of course, a base, and S2- is the anion of the weak diprotic acid, H2S. Find the molar solubility of zinc sulfide in
(a) PH-7.0 water.
(b) A solution containing 0.100 M NH3.
