When NaOH solution is added to aqueous copper (II) sulphate solution, hydroxide ions displace water molecules forming a pale blue precipitate, X. If excess ammonia is now added, water molecules and hydroxide ions are exchanged by ammonia molecules, forming a deep blue solution, Y. Identify X and Y.

Addition of excess aqueous ammonia to a pink coloured aqueous solution of MCl2.6H2O (X) and NH4Cl gives an octahedral complex Y in the presence of air. In aqueous solution, complex Y behaves as 1 : 3 electrolyte. The reaction of X with excess HCl at room temperature results in the formation of a blue coloured complex Z. The calculated spin only magnetic moment of X and Z is 3.87 B.M., whereas it is zero for complex Y.
