The reaction that occurs is a redox reaction. The Copper metal (Cu 0)on the copper pennies is oxidized in concentrated nitric acid to produce Cu 2 + ions. Copper is easily oxidized to Cu 2 +, which is blue in aqueous solutions (water) so you should see the solution turn blue as the copper penny reacts.he Copper metal (Cu 0)on the copper pennies is oxidized in concentrated nitric acid to produce Cu 2 + ions.

The oldest metal object found in the Middle East consists of copper (it was a tiny awl dating back as far as 5100 B.C.). The U.S. penny was originally made of pure copper (nowadays, it is 97.5 percent zinc with a thin copper skin). Copper ranks as third-most-consumed industrial metal in the world, after iron and aluminum, according to the U.S. Geological Survey. About three-quarters of that copper goes to make electrical wires, telecommunication cables and electronics.
