Potassium permanganate Wikipedia

Solid potassium permanganate decomposes when heated 2KMnO 4 → K 2 MnO 4 MnO 2 (s) O 2. Here, the oxidation state of manganese changes as the potassium permanganate (oxidation state 7) decomposes to potassium manganate (oxidation state 6) and manganese dioxide (oxidation state 4). Oxygen gas is also liberated.
