उत्तर
\[\ce{\underset{\text{blue}}{CuSO4} + 2NH4OH -> \underset{\text{pale blue ppt.}}{Cu(OH)2\downarrow} + \underset{\text{colourless in solution}}{(NH4)2SO4}}\]
With excess of NH4OH , ppt. dissolves
\[\ce{Cu(OH)2 + 4NH4OH -> \underset{(Deep Blue Solution)}{\underset{Tetrammine copper (II) hydroxide}{[Cu(NH3)4](OH2)}} + 4H2O}\]
