Potassiumperoxide is a highly reactive, oxidizing white to yellowish solid which, while not flammable itself, reacts violently with flammable materials. It decomposes violently on contact with water. [1]
The standard enthalpy of formation of potassium peroxide is ΔH f 0 = −496 kJ/mol.
Usageedit
Potassium Peroxide is used as an oxidizing agent and bleach (due to the peroxide), and to purify air.
