Question

In the reactions potassium maganate is converted to potassium permaganate the change in the oxidation number of Mn is​

Answer 1

Answer:

Solid potassium permanganate decomposes when heated: 2 KMnO^4→ K^2MnO^4 + MnO^2(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).
