In inorganic nomenclature, a manganate is any negatively charged molecular entity with manganese as the central atom However, the name is usually used to refer to the tetraoxidomanganate(2−) anion, MnO 4, also known as manganate(VI) because it contains manganese in the +6 oxidation state Manganates are the only known manganese(VI) compounds Potassium manganate (VII) solution is used to find the concentration of all sorts of reducing agents It is always used in acidic solution For example, it oxidizes Chemistry of Manganese Chemistry LibreTexts
