When copper (ii) sulphate solution is treated with excess ammonium hydroxide, a precipitate is first formed, and then this dissolves to give a deep blue solution.

This deep blue solution is a?

Cu(OH)₂

CuSo₄.5H₂O

(NH₄)₂SO₄

Cu(NH₃)₄(OH)₂

CuSO₄.(NH₄)₂SO₄.2H₂O

Correct answer is D

\(CuSO_4+2NH_4OH→(NH_4)_2SO_4+Cu(OH)_2\)(pale−blue)

The pale blue precipitate of copper hydroxide dissolves in excess of ammonium hydroxide forming tetraamine copper [II] sulphate, an azure blue(deep blue) soluble complex salt.

\(Cu(OH)_2+(NH_4)_2SO_4+2NH_4OH→[Cu(NH_3)_4]SO_4+4H_2O\)
