20-September-2008 09:29:10 - Oxidizing agent Redirected from Oxidizer European Union Chemical hazard symbol for oxidising agents European Union Chemical hazard symbol for oxidising agents Dangerous goods label for oxidizing agents Dangerous goods label for oxidizing agents An oxidizing agent also called an oxidant or oxidizer 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. In simple terms: 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. A mnemonic for differentiating the reactions is OIL RIG: Oxidation Is Loss, Reduction Is Gain of electrons or LEO the lion says GER Lose Electrons: Oxidation, Gain Electrons: Reduction Contents 1 Example of oxidation 2 Alternate meanings 3 Common oxidizing agents 4 Common oxidizing agents and their products 5 See also Example of oxidation The formation of ironIII oxide; 4Fe + 3O2 → 2Fe2O3 In the above equation, the Iron Fe has an oxidation number of 0 before and 3+ after the reaction. For oxygen O the oxidation number began as 0 and decreased to 2-. These changes can be viewed as two half-reactions that occur concurrently: Oxidation Half Reaction: Fe0 → Fe3+ + 3e- Reduction Half Reaction: O2 + 4e- → 2 O2- Iron III Fe has been oxidized because the oxidation number increased and is the reducing agent because it gave electrons to the oxygen O. Oxygen O has been reduced because the oxidation number has decreased and is the oxidizing agent because it took electrons from iron Fe Alternate meanings Because the process of oxidation is so widespread explosives, chemical synthesis, corrosion, the term oxidizing agent has acquired multiple meanings. One definition, an oxidizing agent receives - or accepts - electrons from a reagent. In this context, the oxidizing agent is called an electron acceptor. A classic oxidizing agent is the ferrocenium ion FeC5H52+ which accepts an electron to form FeC5H52. Of great interest to chemists are the details of the electron transfer event, which can be described as inner sphere or outer sphere. In another more colloquial usage, an oxidizing agent transfers oxygen atoms to the substrate. In this context, the oxidizing agent can be called an oxygenation reagent or oxygen-atom transfer agent. Examples include MnO4- permanganate, CrO42- chromate, OsO4 osmium tetroxide, and especially ClO4- perchlorate. Notice that these species are all oxides, and in fact, polyoxides. In some cases, these oxides can also serve as electron acceptors, as illustrated by the conversion of MnO4- to MnO42-, manganate. The strict dangerous goods definition of an oxidizing agent are substances that, while in themselves not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to, the combustion of other material. Australian Dangerous Goods Code 6th ion By this definition some materials that are classified as oxidizing agents by analytical chemists are not classified as oxidizing agents in a dangerous goods sense. An example is potassium dichromate which does not pass the dangerous goods test of an oxidizing agent. Common oxidizing agents Hypochlorite and other hypohalite compounds such as Bleach Iodine and other halogens Chlorite, chlorate, perchlorate, and other analogous halogen compounds Permanganate salts Ammonium ceriumIV nitrate and probably related CeriumIV compounds Hexavalent chromium compounds such as chromic and dichromic acids and chromium trioxide, Pyridinium chlorochromate PCC, and chromate/dichromate compounds Peroxide compounds Tollen's Reagent Sulfoxides Persulfuric acid Ozone Osmium tetroxide OsO4 Nitric acid Nitrous oxide N2O Common oxidizing agents and their products Agent Products O2 oxygen Various, including the oxides H2O and CO2 O3 ozone Various, including ketones, aldehydes, and H2O; see ozonolysis F2 fluorine F- Cl2 chlorine Cl- Br2 bromine Br- I2 iodine I-, I3- OCl- hypochlorite Cl-, H2O ClO3- chlorate Cl-, H2O HNO3 nitric acid NO nitric oxide NO2 nitrogen dioxide Hexavalent chromium CrO3 chromium trioxide CrO42- chromate Cr2O72- dichromate Cr3+, H2O MnO4- permanganate MnO42- manganate Mn2+ acidic or MnO2 basic H2O2, other peroxides Various, including oxides and H2O See also Reducing agent Organic oxidation Retrieved from http://en..org/wiki/Oxidizing_agent Categories: Electrochemistry | Oxidizing agents Views Article Discussion this page History Personal tools Log in / create account Navigation Main page Contents Featured content Current events Random article Search Go Search Interaction Community portal Recent changes Contact Donate to Help Toolbox What links here Related changes Upload file Special pages Printable version Permanent link Cite this page Languages Deutsch Esperanto Español Eesti Français Lietuvių Nederlands Português Polski РуÑ?Ñ?кий ä¸æ–‡ This page was last modified on 10 July 2008, at 09:40
