Hurricane Harbor Water Park.
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.

At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite-CuFeS2. From the formula, it is clear that iron and sulphur have to be removed in order to produce copper.t this stage of the process, the chemical reactions begin.
