Unveiling Oxidation: A Fundamental Chemical Process

At its core, oxidation is the opposite of reduction, a reaction where a substance gains electrons. Together, these two processes form the basis of redox (reduction-oxidation) reactions, which are essential for life and drive countless chemical transformations.

Think of oxidation as a game of molecular hot potato, where electrons are passed from one molecule to another. The molecule that loses electrons is oxidized, while the molecule that gains electrons is reduced.
