Document Summary

12:21 pm similar questions from quiz on midterm. Stability constants (1) stepwise stability constants --> k ex: put metal in water --> [m(h2o)6]n+ + l [m(h2o)5l]n+ + h2o no redox happeningdon"t change oxidation state have ligand if monodontic, replace 1 water with 1 ligand. -> no change in oxidation state putting in 1 ligand. K1 = products/reactants (don"t include water, don"t include the solvent you"re working in) [m(h2o)5l]n+ + l [m(h2o)4(l)2]n+ + h2o general: mln-1 + l mln. Kn < kn-1 gets progressively harder to put in more ligands has to do w/ sterics. K4 = 1. 51 * 102 gets lowerharder to add more ligands (2) overall stability constants: . N = k1 * k2 * kn if k < 1, then complex doesn"t form there is enthalpy contribution and entropy contribution. Metal = lewis acid (consider metal to be lewis acid)
