Answer»

`FeSO_(4)` solution mixed with `(NH_(4))_(2)SO_(4)` solution in `1:1` molar RATIO GIVES test of `FE^(2+)` ion
`CuSO_(4)` solution mixed with aqueous ammonia in `1:1` molar ratio gives test of `Cu^(2+)` ion
`Aq.CuSO_(4)` solution (blue in colour) gives a green precipitate with aqueous potassium fluoride
`Aq.CuSO_(4)` solution (blue in colour) gives a bright green solution with aqueous potassium chloride

Solution :`CuSO_(4)+4NH_(3) to [Cu(NH_(3))]SO_(4)`
