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 humate Potassium humate Potassium humate is the potassium salt of humic acid. It is manufactured commercially by alkaline extraction of brown coal (lignite) Leonardite to be used mainly as a soil conditioner. The extraction is performed in water with the addition of potassium hydroxide (KOH), sequestering agents and hydrotropic surfactants. Heat is used to increase the solubility of humic acids and hence more potassium humate can be extracted. The resulting liquid is dried to produce the amorphous crystalline like product which can then be added as a granule to fertiliser. The potassium humate granules by way of chemical extraction lose their
