Potassium manganate when [] < 1M, follows bimolecular kinetics. See for a list. Potassium manganate Potassium manganate is the inorganic compound with the formula KMnO. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO), a common chemical. Occasionally, potassium manganate and potassium "per"manganate are confused, but they are different compounds with distinctly different properties. KMnO is a salt, consisting of K cations and MnO anions. X-ray crystallography shows that the anion is tetrahedral, with Mn-O distances of 1.66 Å, ca. 0.03 Å longer than the Mn-O distances in KMnO. It is isostructural with potassium sulfate. The industrial
Potassium oxide Potassium oxide Potassium oxide (KO) 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 KO. Potassium oxide is produced from the reaction of oxygen and potassium; this reaction affords potassium oxide, KO. Treatment of the peroxide with potassium produces the oxide: Alternatively and more conveniently, KO is synthesized by heating potassium nitrate with metallic potassium: Other possibility is to heat potassium
