An aqueous solution of metal ion M₁ reacts separately with reagents Q and R in excess to give tetrahedral and square planar complexes, respectively. An aqueous solution of another metal ion M₂ always forms tetrahedral complexes with these reagents. Aqueous solution of M₂ on reaction with reagent S gives white precipitate which dissolves in excess of S. The reactions are summarised in the scheme give below
