Question
The green paramagnetic species formed by heating ${KMnO}_{4}$ at 513 K is
Options
A.MnO
B.${KO}_{2}$
C.$K_{2}{MnO}_{4}$
D.${Mn}_{3}O_{4}$
Solution
Sol. [Key Concept: K₂MnO₄ (green manganate) from heating KMnO₄]
$2{KMnO}_{4} \rightarrow {\text{ }K}_{2}{MnO}_{4} + {MnO}_{2} + O_{2}$
$K_{2}{MnO}_{4}$ will form on heating ${KMnO}_{4}$ which has green colour.
