👉 Post-reduction is a process in chemistry and biochemistry where a substance undergoes a chemical change, resulting in the production of a new substance. This new substance can be either a product or a byproduct of the initial reaction. For example, when a metal like iron reacts with water to form hydrogen gas and iron(III) oxide, this is considered a post-reduction process because the iron (III) oxide is formed as a result of the chemical change. The iron(III) oxide
