Potassium oxide (K 2 O) is an ionic compound of potassium and oxygen. It is a base. This pale yellow solid is the simplest oxide of potassium. It is a highly reactive compound that is rarely encountered. Some industrial materials, such as fertilizers and cements, are assayed assuming the percent composition that would be equivalent to K 2 O.
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.
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 ↑
Although most compounds are referred to by their IUPAC systematic names (following IUPAC nomenclature), traditional names have also been kept where they are in wide use or of significant historical interests.
Common name Chemical name (Formula) Potash fertilizer: Up to the early 20th century:potassium carbonate (K 2 CO 3). Beginning from the late 19th century: one or more of potassium chloride (KCl), potassium sulfate (K 2 SO 4) or potassium nitrate (KNO 3).
