What is formed when Potassium is heated strongly in oxygen?

Potassium oxide is produced from the reaction of oxygen and potassium; this reaction affords potassium peroxide, K2O2. Potassium forms superoxide (KO2) in reaction with oxygen.

K + O2 → KO2

  • Potassium Superoxide (KO2) is an oxygen (O2) generator, a dehumidifier (removes water content) and a remover of carbon dioxide (CO2).
  • It is a yellow paramagnetic solid that decomposes in moist air.
  • Potassium superoxide (KO2) is used in oxygen cylinders in space and submarines because it acts as an oxygen generator.
