${KMnO}_{4}$ decomposes on heating at $513 K$ to form $O_{2}$ along with

Options:

Answer:

Solution:

Potassium permanganate decomposes when heated, the oxidation state of manganese changes as the oxidation state of ${KMnO}_{4}$ is $+ 7$ decomposes to potassium manganate which oxidation state is $+ 6$ and manganese dioxide its oxidation state is $+ 4$ .

It is a redox reaction in which $Mn$ which undergo both oxidation and reduction such type of reaction is known as a disproportionation reaction.

$2 {KMnO}_{4} \overset{513 K}{\to} K_{2} {MnO}_{4} + {MnO}_{2} + O_{2}$
