Ligand Substitution (A-level Chemistry)

Outlining what ligand substitution reactions are, including changes in co-ordination number and the role of monodentate (water, ammonia and chloride), bidentate (such as diamines and ethanediate ions) and multidentate (such as EDTA) ligands. Ligand substitution and entropy change as well as the chelate effect is shown with substitution of monodentate with bidentate and multidentate ligands.

Hi, is there a way to predict how many ligands will be substituted? I know that for some copper aqua ion reactions not all the aqua ligands are substitued (I.e. with ammonia where there are three ammonia and 2 water ligands). If there isn't a way to work this out is there a resource which has all of the complex ion formulae you need to know you one acn memorise how many of each kind of ligand there are in each? Many thanks!!
