WebAn oxidizing agent (often referred to as an oxidizer or an oxidant) is a chemical species that tends to oxidize other substances, i.e. cause an increase in the oxidation state of the substance by making it lose electrons. Common examples of oxidizing agents include halogens (such as chlorine and fluorine), oxygen, and hydrogen peroxide (H 2 O 2 ). WebSuper alkaline ionized water has a redox unit of more than -900mV (as produced). Oxidation and reduction work on the object. When oxidized, metals rust, plants wilt and discolour, and animals age and weaken. The opposite action that prevents these is called reduction. High rust prevention effect flack tours
