Sodium superoxide | NaO2+ | CID 61542 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, … Disodium pentasulphide: Na 2 S 5. Disodium sulphide: Na 2 S. Disodium persulphide: Na 2 S 2. The stability of metal superoxides depends on the size and the electropositive character of the metal. The alkaline earth metals…, In the superoxide ion, O2−, the oxygen has an oxidation number of −1/2. Mixtures with combustible materials (most organic compounds) are readily ignited by … SODIUM SUPEROXIDE violently decomposes above 250°C, evolving oxygen [Mellor 2 Supp. It is an intermediate in the oxidation of sodium by oxygen. Sodium superoxide is the inorganic compound with the formula NaO2. When it is mixed with any combustible material it readily ignites by heat, contact with moisture, or by friction. A superoxide, also known as hyperoxide,is a compound that contains the superoxide anion with the chemical formula O2−. Alkali metals (which have a +1 oxidation state) form oxides, M2O, peroxides, M2O2, and superoxides, MO2. On a larger scale, Disodium dioxide can be prepared by reacting metallic sodium with oxygen at a temperature range of 130 to 200 °C.
