(B) When an aqueous solution of ammonia $(NH_{4}OH)$ is added to a solution of cupric sulfate $(CuSO_{4})$,a pale blue precipitate of copper$(II)$ hydroxide $(Cu(OH)_{2})$ is formed initially.The chemical reaction is: $CuSO_{4}(aq) + 2NH_{4}OH(aq) \rightarrow Cu(OH)_{2}(s) + (NH_{4})_{2}SO_{4}(aq)$.Upon adding excess ammonia,this precipitate dissolves to form a deep blue complex,tetraamminecopper$(II)$ sulfate.

When an aqueous solution of ammonia is added to an aqueous solution of cupric sulfate,which substance forms a pale blue precipitate?
