This page discusses the various definitions of oxidation and reduction (redox) in terms of the transfer of oxygen, hydrogen, and electrons. It also explains the terms oxidizing agent and …

Aug 1, 2020 · Oxidation is the loss of electrons or increase in oxidation state of a molecule, atom, or ion in a chemical reaction. The opposite process is called reduction, which is a gain of …

Common oxidizing agents are oxygen, hydrogen peroxide, and the halogens. In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one …

Jun 7, 2024 · Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction. When oxidation occurs, the oxidation state of the chemical species …

It causes an increase in the oxidation state of the substance by making it lose electrons. Common examples of oxidising agents include halogens (such as chlorine and fluorine), oxygen, and …

Nov 13, 2025 · Because of their complementary nature, the oxidation and reduction processes together are referred to as redox reactions. The reactant that brings about the oxidation is …

Because electrons are neither created nor destroyed in a chemical reaction, oxidation and reduction are linked. It is impossible to have one without the other, as shown in the figure below.

The term oxidation was originally used to describe chemical reactions involving O 2, but its meaning has evolved to refer to a broad and important reaction class known as oxidation …

Oxidation is a chemical process in which a substance loses electrons to another substance. This process can result in the formation of a new chemical species, such as an oxide or a salt, and …

Jul 19, 2025 · To be oxidized means a substance has chemically changed from its interaction with oxygen or a similar substance. This transformation alters the fundamental properties of the …
