A solution containing cadmium (II) ions and ammonia will contain several species. Cd2+ forms complexes with ammonia, where the number of ammonia ligands (NH3) attached to the cadmiuml ion can be vary from one to four. And, of course, ammonia is a base so there will be some NH4+ in solution also. Assume that the concentration of unprotonated NH3 is 0.040 M.
a) What fraction of the cadmium ions are in the form of Cd2+?
b) What fraction of the cadmium ions are in the form of Cd(NH3)22+?
