(b) Consider the equilibria [Cu(H2?O)6?]2+(aq)?+4NH3(aq)??[Cu(NH3?)4?(H2?O)2?]2+(aq)?+4H2?OKeq ?=1.1×1010[Cu(H2?O)6?]2+(aq)?+2en(aq)??[Cu(en)2?(H2?O)2?]2+(aq)?+4H2?OKeq?=3.9×1019 (en =NH2?CH2?CH2?NH2? ). ? Interpret the values of Keq ? : What do these values tell you about the ligands NH3? versus H2?O ? Why is ethylene diamine complex value of Keq? so much different from that of the ammine complex?
