Potassium oxide
Potassium oxide is a member of the class of compounds known as alkali metal hydroxides. Alkali metal hydroxides are inorganic compounds in which the largest oxoanion is hydroxide, and in which the heaviest atom not in an oxoanion is an alkali metal. Potassium oxide can be found in cottonseed and tamarind, which makes potassium oxide a potential biomarker for the consumption of these food products. Potassium oxide (K2O) is an ionic compound of potassium and oxygen. This pale yellow solid, the simplest oxide of potassium, is a rarely encountered, highly reactive compound. Some materials of commerce, such as fertilizers and cements, are assayed assuming the percent composition that would be equivalent to the chemical compound mixture K2O .
