Oxidens

Oxidens is a term occasionally used in chemical literature to refer to species that participate in oxidation reactions. In mainstream chemistry the concept is described by the term oxidants or oxidizing agents; oxidens is not widely adopted as a formal category. When used, it typically denotes a chemical species that accepts electrons in a redox process.

An oxiden can be defined as a chemical species that promotes oxidation by acting as an electron acceptor. This places oxidens on the oxidant side of a redox couple, opposite reductants, which donate electrons. The strength of an oxiden is often described by its redox potential, with more positive potentials indicating stronger oxidants capable of oxidizing weaker substrates.

Examples and classes: Inorganic oxidens include molecular oxygen, hydrogen peroxide, ozone, and halogens such as fluorine and chlorine, as well as permanganate. Organic oxidens include certain hypervalent iodine reagents and nitrosating agents. Classification depends on context, with oxidens selected to achieve desired reactivity and selectivity in synthesis, disinfection, or energy-related processes.

Mechanisms and measurement: Oxidation can proceed by outer-sphere electron transfer, inner-sphere transfer, or atom transfer in some cases. Redox potential, solvent, temperature, and substrate influence outcomes. Measurements include standard redox potentials, stoichiometry, and observed changes in oxidation states.

Applications and safety: Oxidens are central to synthesis, environmental chemistry, and various industrial processes. Many oxidants are highly reactive and can be hazardous; proper storage, compatibility checks, and handling protocols are essential to prevent exothermic reactions or toxic byproducts.
