Chemical compound
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 permanganate are confused, but each compound's properties are distinct.
