Why is it never straightforward?
In the above reaction between hydrogen and oxygen gases, oxygen is the oxidizing agent. Oxygen is a good oxidizer in reactions. Further, hydrogen peroxide, sulfuric acid, nitric acid, halogens, permanganate compounds, and Tollenâs reagent are some of the common oxidizing agents. Reducing Agent.
