An aqueous solution of metal ion M_(1) reacts separately with reagents Q and R in excess to gie tetrahedral and sqaure planar complexes, respectively. An aqueous solution of another metal ion M_(2) always forms tetrahedral complexes with these reagents. Aqueous solution of M_(2) on reaction with reagent S gives white precipitate which dissolves in excess of S. The reaction are summarised in the scheme given below Scheme Reagent S is

An aqueous solution of metal ion M_(1) reacts separately with reagents

1.	An aqueous solution of metal ion M_(1) reacts separately with reagents Q and R in excess to gie tetrahedral and sqaure planar complexes, respectively. An aqueous solution of another metal ion M_(2) always forms tetrahedral complexes with these reagents. Aqueous solution of M_(2) on reaction with reagent S gives white precipitate which dissolves in excess of S. The reaction are summarised in the scheme given below Scheme Reagent S is
