Ligand exchange reactions

At the end of this activity, students should be able to:
– describe the stability of a complex in terms of formation constant
– explain the reaction of aqua ions with ammonia and describe the structure of the resulting ammine complexes
– describe metal complexes of chloride ions
– explain why the complexes with multidentate ligands (chelating agents) are usually more stable than those with unidentate ligands
– explain why the formation of complex ions affects the solubility of ionic compounds.
