Question

Action of heat on potassium permanganate at $746\mathrm{K}$ results in formation of ________.

Answer 1

The reaction of heating potassium permanganate is:

${\mathrm{KMnO}}_4\stackrel{∆}{\to {\mathrm{K}}_2}{\mathrm{MnO}}_4+{\mathrm{MnO}}_2+{\mathrm{O}}_2$

On heating, potassium permanganate gives potassium manganate, manganese dioxide and oxygen as the products.

Therefore,action of heat on potassium permanganate at $746\mathrm{K}$ results in formation of potassium manganate and oxygen.
