Hola, iam Richard Burkett, I hope all goes well today.
Why Does Copper And Nitric Acid Turn Blue? [Solved]
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 Cu2+ ions. Copper is easily oxidized to Cu2+, which is blue in aqueous solutions (water) so you should see the solution turn blue as the copper penny reacts.3 Jan 2009
