What happens when copper ions react with ammonia?

WebCopper oxide (CuO) is a black solid and produced copper has red-brown color. 3CuO (s) + 2NH 3 (g) → N 2 (g) + Cu (s) + 3H 2 O (l) So CuO does not show a catalytic behavior with ammonia gas because amount of CuO is reduced when reaction is in progress. So Cu and CuO behave differently with ammonia. Questions WebCopper (II) ion reacts with stoichiometric quantities of aqueous ammonia to precipitate light blue Cu (OH) 2. Some basic salts may also form. The precipitate does not dissolve in excess sodium hydroxide unless the NaOH solution is very concentrated. What is the name of AG NH3 2 Cl?
