When the copper (II) sulphate solution is reacted with a bidentate ligand such as ethylenediamine (en), the same thing would have happened. However, since one bidentate ligand has two donor atoms (Brown et al, 2017), each Cu2+ ion would only have 3 ligands at most, instead of 6 when reacted with monodentate ligands. The equation of the reaction is as follows: [Cu(H2O)6]2+(aq) + 3en(aq) → [Cu(en)3](aq) + 6H2O(ℓ) a. How do we know how many ligands can enter? b. Explain briefly the discussion above.
