All rights reserved. A superoxide is a compound that contains the superoxide ion, which has the chemical formula O 2. This yellow-orange solid is a salt of the superoxide anion. Oxides Oxides are chemical compounds with one or more oxygen atoms combined with another element. Hayyan M., Hashim M.A., AlNashef I.M., Superoxide Ion: Generation and Chemical Implications, Chem. You can reference the WebElements periodic table as follows:"WebElements,, accessed November 2020. Mixtures with combustible materials (most organic compounds) are readily ignited by … The product is paramagnetic, as expected for a salt of the O−2 anion. The data on these compounds pages are assembled and adapted from the primary literature and several other sources including the following. Gerrans, P. Hartmann-Petersen , p.243 "sodium oxides" ,, Articles containing unverified chemical infoboxes, Articles with unsourced statements from July 2010, Creative Commons Attribution-ShareAlike License, This page was last edited on 24 June 2020, at 18:31. It has a role as a human metabolite, an Escherichia coli metabolite and a … Superoxide is a diatomic oxygen, an inorganic radical anion, an oxygen radical and a member of reactive oxygen species. Superoxide dismutase (SOD, EC is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O 2 −) radical into ordinary molecular oxygen (O 2) and hydrogen peroxide (H 2 O 2).Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. It is an intermediate in the oxidation of sodium by oxygen. Sasol Encyclopaedia of Science and Technology , G.C. E.g. Reacts with water, acids, mono and dioxide of carbon. An oxide is any chemical compound that contains one or more oxygen atoms. SODIUM SUPEROXIDE violently decomposes above 250°C, evolving oxygen [Mellor 2 Supp. Element analysis. It can also be prepared by careful oxygenation of a solution of sodium in ammonia: It is also produced, along with sodium peroxide, when sodium is stored under inappropriate conditions (e.g. 2:639 1961]. The table shows element percentages for NaO 2 (sodium superoxide). Reacts with carbon dioxide to give sodium carbonate and oxygen. A strong oxidizer. The table shows element percentages for NaO2 (sodium superoxide). Sodium superoxide appears as a solid. Molecular oxygen (dioxygen) is a diradical containing two unpaired electrons, and superoxide results from the addition of an electron which fills one of the two degenerate molecular orbitals, leaving a charged ionic s… SODIUM SUPEROXIDE NaO2. Ion has the structure of the (Na +) (O2-). The following are some synonyms of sodium superoxide: The oxidation number of sodium in sodium superoxide is 1. Stephen E. Stephanou, Edgar J. Seyb Jr., Jacob Kleinberg "Sodium Superoxide" Inorganic Syntheses 1953; Vol. Rev., 2016, 116 (5), pp 3029–3085. Copyright 1993-2020 Mark Winter [ The University of Sheffield and WebElements Ltd, UK]. 4, 82-85. The chart below shows the calculated isotope pattern for the formula NaO2 with the most intense ion set to 100%. CO2 , SO2 , CO, ZnO , H2O Peroxides A peroxide is a compound containing an oxygen–oxygen single bond or the peroxide anion, O 2 2− . It is an intermediate in the oxidation of sodium by oxygen. Sodium superoxide is the inorganic compound with the formula NaO2. Obtaining sodium superoxide: Na2O2 + … ", Chemical Rubber Company handbook of chemistry and physics, F.A. Murillo, and M. Bochmann, in. Prolonged exposure to fire or heat may cause vigorous decomposition and the … An oxidizing agent. Cotton, G. Wilkinson, C.A. WebElements: THE periodic table on the WWW [] Oxides can be oxides containing oxide anions (O 2-), peroxides containing peroxide anions (O –) or superoxides containing superoxide anion (O 2 –).A peroxide is any compound that is composed of an oxygen-oxygen single bond.This can be either in the form of an … Yellowish at room temperatures but may become white when cooled. The systematic name of the anion is dioxide(1−). NaO2 is prepared by treating sodium peroxide with oxygen at high pressures:[2]. Except where otherwise noted, data are given for materials in their. in dirty or partially halogenated solvents)[citation needed]. [3] It crystallizes in the NaCl motif. [1] This yellow-orange solid is a salt of the superoxide anion. Main Difference – Peroxide vs Superoxide. Sodium superoxide is the inorganic compound with the formula NaO2. It hydrolyses readily to give a mixture of sodium hydroxide, oxygen and hydrogen peroxide. Properties of sodium superoxide NaO2: The orange-yellow, when heated decomposes without melting. The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O2, which occurs widely in nature.
