Answer:

Solid potassium permanganate decomposes when heated: 2 KMnO4 → K2MnO4 + MnO2(s) + O. 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.
