In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula O − 2. [1] The systematic name of the anion is dioxide(1−).The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O 2, which occurs widely in nature. [2]
The hydroperoxyl radical, also known as the hydrogen superoxide, is the protonated form of superoxide with the chemical formula HO 2, also written HOO •. This species plays an important role in the atmosphere and as a reactive oxygen species in cell biology.
Potassium superoxide is an inorganic compound with the formula K O 2. [6] It is a yellow paramagnetic solid that decomposes in moist air. It is a rare example of a stable salt of the superoxide anion. It is used as a CO 2 scrubber, H 2 O dehumidifier, and O 2 generator in rebreathers, spacecraft, submarines, and spacesuits.
superoxide (O − 2) is produced by reduction of O 2. [4] Several grams are produced per day in the human body within the mitochondria. [5] O 2 + e − → O − 2. Competing with its formation, superoxide is destroyed by the action of superoxide dismutases, enzymes that catalyze its disproportionation: 2 O − 2 + 2H + → O 2 + H 2 O 2
Potassium superoxide (KO 2) is a yellow solid that decomposes at 560 °C. It is used as a CO 2 scrubber, H 2 O dehumidifier, and O 2 generator in rebreathers, spacecraft, submarines, and spacesuit life support systems. Rubidium superoxide (RbO 2) is produced when rubidium burns in air. Caesium superoxide (CsO 2) is produced when caesium burns ...
Sodium superoxide is the inorganic compound with the formula Na O 2. [1] This yellow-orange solid is a salt of the superoxide anion. It is an intermediate in the oxidation of sodium by oxygen.

Potassium peroxide is an inorganic compound with the molecular formula K 2 O 2. It is formed as potassium reacts with oxygen in the air, along with potassium oxide (K 2 O) and potassium superoxide (KO 2). Crystal structure. Potassium peroxide reacts with water to form potassium hydroxide and oxygen: 2 K 2 O 2 + 2 H 2 O → 4 KOH + O 2 ↑
