Trivalent chromium (III) is an essential trace metal necessary for the formation of glu … WebCommon oxidizing agents are oxygen, hydrogen peroxide and the halogens . In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one or more electrons. In that sense, it is one component in an oxidation–reduction (redox) reaction.
