 Oxidizing agent
  • Oxidizing agent
  • An oxidizing agent (also called an oxidant, oxidizer or oxidiser) can be defined as either: a chemical compound that readily transfers oxygen atoms, or a substance that gains electrons in a redox chemical reaction. In both cases, the oxidizing agent becomes reduced in the process.The oxidizing agent is reduced. The reducing agent is oxidized. All atoms in a molecule can be assigned an oxidation number. This number changes when an oxidant acts on a substrate. Redox reactions occur when oxidation states of the reactants change.

    Common oxidizing agents

    peroxide and other inorganic Peroxides
    and s
    Chlorite, chlorate, perchlorate, and other analogous halogen compounds
    Hypochlorite and other hypohalite compounds such as bleach
    and other halogens

    (N2O)
    oxide
    salts
    Hexavalent chromium compounds such as chromic and dichromic acids and chromium trioxide, pyridinium chlorochromate (PCC), and chromate/dichromate compounds
