Zinc sulfide, ZnS, is sparingly soluble under most situations. With ammonia, Zn2+, forms four complexes, Zn(NH3)2+, Zn(NH3)2+2, 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 9.00 ammonia/ammonium ion buffer with a total NH3/NH4+ concentration of 0.100 M b) The same solution as a but it also contains 0.100 M EDTA
