Oxidation-Reduction Reactions - Chemistry LibreTexts

An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron. Redox reactions are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting.

Oxidation - Simple English Wikipedia, the free encyclopedia

Oxidation and reduction together are called redox (reduction and oxidation). Oxygen does not have to be present in a reaction for it to be a redox-reaction. Oxidation is the loss of electrons. In terms of oxygen transfer, oxidation may be defined as the chemical process in which a substance gains oxygen or loses electrons and hydrogen. When one .

This overall reaction is also a reduction oxidation process that involves a flow of electrons, just like our zinc and copper example. The flow of electrons however may not be as clear here. So I just want to take a minute and review the oxidation and reduction from more of a biological perspective, by looking at this reaction.

Because both reduction and oxidation are occurring simultaneously, this is known as a redox reaction. An oxidizing agent is substance which oxidizes something else. In the above example, the iron(III) oxide is the oxidizing agent. A reducing agent reduces something else. In the equation, the carbon monoxide is the reducing agent.
