Answer»

Solution :When excess of liquid ammonia is ADDED to an aqueous solution of copper sulphate to GIVE tetraamminecopper (II) sulphate
`underset(("Copper Sulphate"))(CuSO_(4)) + underset("(Ammonia)")(4NH_(3)) rarr underset(("TETRAMMINECOPPER (II) Sulphate"))([Cu(NH_(3))_(4)] SO_(4))`
Therefore, the coordination ENTITY is `[Cu(NH_(3))_(4)]^(2+)`
