ammonia is reducing.
Under certain conditions, ammonia can react with copper oxide, which is ammonia reduction of copper oxide, then how to reduce it?
Copper oxide can be reduced by charcoal, carbon monoxide, hydrogen, ammonia, active metals, such as magnesium, iron, etc., but generally these reduction reactions do not have any economic value, most of which occur in the laboratory.
Ammonia and copper oxide reaction, is a REDOX reaction, ammonia as reducing agent, copper oxide is the oxidant.
If the reaction rate of ammonia reduction of copper oxide is found to be slow, copper oxide can be heated to speed up the reaction rate.
The chemical equation of ammonia and copper oxide reaction: 3CuO+2NH3 = 3Cu+3H2O+N2 (heating conditions).
