Oxidation vs. Reduction: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 19, 2023
Oxidation involves loss of electrons; reduction involves gain of electrons.

Key Differences

In the realm of chemistry, oxidation and reduction are two processes that are intertwined. Oxidation is an event where an atom, ion, or molecule loses electrons, typically but not always, resulting in an increase in its oxidation state. On the flip side, reduction is a chemical reaction where electrons are acquired, leading to a decrease in the oxidation state.

Fundamentally, oxidation cannot occur without a corresponding reduction; this tandem action is known as a redox (reduction-oxidation) reaction. For instance, in the reaction where hydrogen reacts with oxygen to produce water, hydrogen undergoes oxidation by losing electrons, while oxygen undergoes reduction by gaining those electrons.

It's essential to realize that these processes don't only concern electron transfer. Sometimes, oxidation might be perceived as the addition of oxygen or removal of hydrogen, whereas reduction can be seen as the addition of hydrogen or the removal of oxygen.
