Answer:

HCl, a black precipitate is obtained. On boiling the precipitate with dil. HNO_{3} it forms a solution of blue colour. Addition of excess of aqueous solution of ammonia to this solution gives.

In qualitative analysis when H₂S is passed through an aqueous solution of salt acidified with dil. HCl, a black precipitate is obtained. On boiling the precipitate with dil. HNO₃ it forms a solution of blue colour.

And, on addition of excess of aqueous solution of ammonia to this solution gives a complex deep blue solution of [Cu(NH₃)₄]²⁺
