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 low melting point.
A permanganate (/ p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) [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]
With sodium hydroxide, the end product is not sodium manganate but an Mn(V) compound, which is one reason why the potassium permanganate is more commonly used than sodium permanganate. Furthermore, the potassium salt crystallizes better. [36] The potassium manganate is then converted into permanganate by electrolytic oxidation in alkaline media:
Manganates are the only known manganese(VI) compounds. [2] Other manganates include hypomanganate or manganate(V), MnO 3− 4, permanganate or manganate(VII), MnO − 4, and the dimanganate or dimanganate(III) Mn 2 O 6− 6. A manganate(IV) anion MnO 4− 4 has been prepared by radiolysis of dilute solutions of permanganate.

Potassium manganate is the inorganic compound with the formula K 2 MnO 4. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO 4), a common chemical. [1] Occasionally, potassium manganate and potassium permanganate are confused, but each compound's properties are distinct.
Sodium manganate is the inorganic compound with the formula Na 2 Mn O 4. This deep green solid is a rarely encountered analogue of the related salt K 2 MnO 4 . Sodium manganate is rare because it cannot be readily prepared from the oxidation of manganese dioxide and sodium hydroxide.
Sodium perrhenate (also known as sodium rhenate(VII)) is the inorganic compound with the formula NaReO 4. It is a white salt that is soluble in water. It is a common precursor to other rhenium compounds. Its structure resembles that of sodium perchlorate and sodium permanganate.
