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 pyrosulfate Potassium pyrosulfate Potassium pyrosulfate, or potassium disulfate, is an inorganic compound with the chemical formula KSO. Potassium pyrosulfate is obtained by the thermal decomposition of other salts, most directly from potassium bisulfate: Temperatures above 600°C further decompose potassium pyrosulfate to potassium sulfate and sulfur trioxide however: Other salts, such as potassium trisulfate, can also decompose into potassium pyrosulfate. Potassium pyrosulfate contains the pyrosulfate anion which has a dichromate like structure. The geometry can be visualized as a tetrahedron with two corners sharing the SO anion's configuration and a centrally bridged oxygen atom. A semi-structural formula for the pyrosulfate anion is
