Question

potassium permanganate = potassium manganate + manganese dioxide+ oxygen​

Answer 1

Answer:

Potassium permanganate will decompose into potassium manganate, manganese dioxide and oxygen gas: 2KMnO4 → K2MnO4 + MnO2 + O. This reaction is a laboratory method to prepare oxygen, but produces samples of potassium manganate contaminated with MnO2.

Answer 2

Answer:

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 they are different compounds with distinctly different properties.
