COPPER METAL REACTS WITH NITRIC ACID
Copper Metal In A Beaker Of Nitric Acid
Oxidation of copper metal by nitric acid produces nitric oxide (NO) gas which is immediately oxidized in air to form brown nitrogen dioxide (NO2) gas. The copper atoms lose two electrons to form Cu2+ ions which give a blue color in water.
