Oxidize

Oxidation is a chemical reaction that involves the moving of electrons from one substance to another. More specifically, it refers to the substance that gives away electrons. In the process of oxidation, the substance that gives away electrons is said to be oxidized.

Process of Oxidation

The process of oxidation involves the loss of electrons or an increase in oxidation state by a molecule, atom, or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or a decrease in oxidation state by a molecule, atom, or ion.

Oxidizing Agents

An oxidizing agent (also known as an oxidant, oxidizer, or oxidiser) can be a substance that has the ability to oxidize other substances — in other words, to cause them to lose electrons. Some examples of oxidizing agents include halogens, potassium nitrate, and nitric acid.

Biological Oxidation

In biological systems, oxidation and reduction processes are vital for life. These processes, collectively known as redox reactions, play a key role in cellular respiration and photosynthesis. In cellular respiration, glucose and other organic molecules are oxidized to produce energy.

Oxidation in Food Industry

In the food industry, oxidation can lead to spoilage. This is why antioxidants are added to some foods to prevent oxidation and extend shelf life.
