A permanganate (/ pərˈmæŋɡəneɪt, pɜːr -/) [1] is a chemical compound with the manganate (VII) ion, MnO−. 4, the conjugate base of permanganic acid. Because the manganese atom has a +7 oxidation state, the permanganate (VII) ion is a strong oxidising agent. The ion is a transition metal ion with a tetrahedral structure. [2]
It is a purplish-black crystalline salt, that dissolves in water as K + and MnO−4, an intensely pink to purple solution. Potassium permanganate is widely used in the chemical industry and laboratories as a strong oxidizing agent, and also as a medication for dermatitis, for cleaning wounds, and general disinfection.
Potassium permanganate, KMnO 4, is a widely used, versatile and powerful oxidising agent. Permanganic acid solutions are unstable, and gradually decompose into manganese dioxide, oxygen, and water, with initially formed manganese dioxide catalyzing further decomposition. [6] Decomposition is accelerated by heat, light, and acids.
Infobox references. Sodium permanganate is the inorganic compound with the formula Na MnO 4. It is closely related to the more commonly encountered potassium permanganate, but it is generally less desirable, because it is more expensive to produce. It is mainly available as the monohydrate. This salt absorbs water from the atmosphere and has a ...

Potassium manganate is the inorganic compound with the formula K2MnO4. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO4), a common chemical. [ 1 ] Occasionally, potassium manganate and potassium per manganate are confused, but each compound's properties are distinct.
Properties. Chemical formula. Mg (MnO 4) 2. Solubility in water. soluble. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Magnesium permanganate is an inorganic compound with the chemical formula Mg (MnO 4) 2. It can be used as an oxidant.
Dihydroxylation. Dihydroxylation is the process by which an alkene is converted into a vicinal diol. Although there are many routes to accomplish this oxidation, the most common and direct processes use a high-oxidation-state transition metal (typically osmium or manganese). The metal is often used as a catalyst, with some other stoichiometric ...
