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 bifluoride it to generate, for the first time, hydrogen fluoride. Potassium bifluoride is prepared by treating potassium carbonate or potassium hydroxide with hydrofluoric acid: The electrolysis of KHF was used by Henri Moissan to isolate the element fluorine in 1886. A related material containing two equivalents of HF is also known, KHF (CAS#12178-06-2, m.p. 71.7 C). The industrial production of fluorine entails the electrolysis of molten KHF. Potassium bifluoride Potassium bifluoride is the inorganic compound with the formula KHF. This colourless salt consists of the potassium cation and the bifluoride (HF) anion. The salt is used in etchant for glass. Sodium
