Oxidizing agent - Wikipedia
An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
What Is an Oxidant? Definition of Chemistry Terms - ThoughtCo
This is the definition of an oxidant in chemistry, along with examples of common oxidizers and a look at how they work.
What Is an Oxidant in the Body and What Does It Do?
An oxidant in the body is a reactive molecule that strips electrons from other molecules, altering their structure and function. The most common oxidants are a group called reactive oxygen species (ROS), which include superoxide, hydrogen peroxide, and hydroxyl radicals. Your body produces these molecules constantly as a normal byproduct of being alive, and in small amounts they serve ...
OXIDANT Definition & Meaning - Merriam-Webster
The meaning of OXIDANT is oxidizing agent. On the metal surface, PMS and chloride ions (Cl⁻) are activated, producing highly reactive oxidants such as singlet oxygen and hypochlorous acid. Georgina Jedikovska, Interesting Engineering, 8 Jan. 2026 That stress, which arises from an excess of free radicals and a dearth of anti-oxidants, causes cells to stop working and thus eventually die. New ...
Oxidizing and Reducing Agents - Chemistry LibreTexts
Oxidizing and Reducing Agents An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction. Also known as the electron acceptor, the oxidizing agent is normally in one of its higher possible oxidation states because it will gain electrons and be reduced. Examples of oxidizing agents include halogens, potassium nitrate, and nitric acid. A reducing agent, or reductant ...
Explainer: What are oxidants and antioxidants?
Antioxidants are chemicals that may help fight damage due to disease and aging. These powerful compounds work by blocking what’s known as oxidation. That’s a type of natural chemical reaction (often involving oxygen). And this reaction can harm cells. The molecules that trigger oxidation are called oxidants. Chemists tend to also refer to these as free radicals (or sometimes just radicals ...
Redox - Wikipedia
"Redox" is a portmanteau of "reduction" and "oxidation". The term first appeared in a 1928 article by Leonor Michaelis and Louis B. Flexner. [5][6] Oxidation is a process in which a substance loses electrons. Reduction is a process in which a substance gains electrons. The processes of oxidation and reduction occur simultaneously and cannot occur independently. [7] In redox processes, the ...
What Is an Oxidant? The Chemical and Biological Meaning
An oxidant is a chemical agent that participates in oxidation-reduction (redox) reactions, which involve the movement of electrons between substances. This agent acts by accepting electrons from another molecule, resulting in a chemical change for both participants. This process is a basic principle in chemistry, materials science, and has a profound impact on biological systems and human ...
