Answer:
CuSO4(aq) + 4NH3(aq) + nH2O→ [Cu(NH3)4H2On]S04(aq)
Explanation:
When the concentrated ammonia is added into the copper ions solution, a blue solid is formed. This blue solid is gelatinous.it consist of Cu(OH)2 in insoluble form. As more ammonia is added precipitate start to dissolve and [Cu(NH3)4]∧+2 is produce.
Net Ionic equation:
Cu∧+2 +4NH3 → [Cu(NH3)4]∧+2
S04∧-2 are spectator ions.
Properties and uses of Tetraaminecopper(ll) sulfate:
1. It is solid compound.
2. Its color is dark blue.
3. It has ammonia like odor.
4. It is used to make the copper compounds and also used in the printing of fabric.
