Oxidizer Definition in Chemistry

An oxidizer, also known as an oxidant or oxidizing agent, is a reactant that removes electrons from other reactants during a redox reaction. It may also be considered to be a chemical species that transfers electronegative atoms to a substrate. The word origin derives from the transfer of oxygen, but the definition has since been expanded to include other species in a redox reaction. Oxidizer Examples Hydrogen peroxide, ozone, and nitric acid are all oxidizers. The halogens are all excellent oxidizing agents. Naturally, oxygen (O2) and ozone (O3) are oxidizers.
