Write down the reaction equation and make the ORP of barium with dilute nitric acid.

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

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

The electronic equation of the reaction is as follows:

8 Ba ° – 2 e → Ba 2+ reducing agent

2 N 5+ + 8e → N3- oxidizing agent.
