Vedclass · Answer

(A) When potassium permanganate $(KMnO_4)$ is heated at $513 \ K$, it undergoes thermal decomposition to form potassium manganate $(K_2MnO_4)$, manganese dioxide $(MnO_2)$, and oxygen gas $(O_2)$.The chemical equation for the reaction is:$2KMnO_4 \xrightarrow{513 \ K} K_2MnO_4 + MnO_2 + O_2$In $K_2MnO_4$, the manganese is in the $+6$ oxidation state $(Mn^{6+})$, which has a $d^1$ electronic configuration. Due to the presence of one unpaired electron, $K_2MnO_4$ is paramagnetic and exhibits a characteristic green color.
