Potassium superoxide should not be added to pure organic materials (hydrocarbons), as ignition and violent explosion may occur. 1. Oxidation of arsenic, antimony, copper, potassium, tin, or zinc proceeds with incandescence, [Mellor, 1941, Vol. Display Name: Potassium superoxide EC Number: 234-746-5 EC Name: Potassium superoxide CAS Number: 12030-88-5 Molecular formula: KO2 IUPAC Name: potassium oxidanone 1967]. Oxidation of arsenic, antimony, copper, potassium, tin, or zinc proceeds with incandescence, [Mellor, 1941, Vol. 1967]. 2, 493]. 16) What is the oxidation number of each oxygen in the compound, potassium superoxide? Potassium superoxide was considered the cause of the reaction [Health and Safety Inf. Potassium superoxide should not be added to pure organic materials (hydrocarbons), as ignition and violent explosion may occur. It is a rare example of a stable salt of the superoxide anion. It is a yellow paramagnetic solid that decomposes in moist air. Potassium superoxide was considered the cause of the reaction [Health and Safety Inf. 15) What is the oxidation number of each oxygen atom in the compound, sodium peroxide? For starters, the structure of potassium superoxide is KO2 in which O2 as a whole unit has an oxidation number of -1 because potassium, the positive ion has the oxidation number +1. 2, 493]. Potassium superoxide is the inorganic compound with the formula KO 2. Potassium superoxide is used as a CO 2 scrubber, H 2 O dehumidifier and O 2 generator in rebreathers, spacecraft, submarines and spacesuit life support systems 251. 251.
