Write down the reaction equation for the interaction of dilute nitric acid with Cu and the redox reaction.

For an example of a redox reaction with nitric acid, let’s take active copper. The example of this reaction is the easiest to trace a reaction of this kind. This is due to the fact that, according to the condition, our nitric acid is diluted, and copper actively reacts with it. As a result of the reaction, a copper nitrate salt is formed, ammonium nitrate is also formed and water is released. The chemical equation for the reaction is as follows:

4 Cu + 10 HNO3 = 4 Cu (NO3) 2 + NH4NO3 + 3 H2O

The electronic equation of the reaction is as follows:

8 Cu ° – 2 e → Ba 2+ reducing agent

2 N 5+ + 8e → N3- oxidizing agent.
