Question

The compounds formed when $KMnO _{4}$ is heated to $513\, K$ are______

• A. $MnO _{2}, O _{2}$ and $KOH$
• B. $K _{2} MnO _{4}, MnO _{2}$ and $O _{2}$
• C. $K _{2} MnO _{4}, MnO _{2}$ and $H _{2} O$
• D. $MnO, MnO_{2}$ and $O_{2}$

Answer 1

Answer: (B)

$\underset{\text { Potassium permanganate }}{2KMmO_4} \xrightarrow{513\, K } \underset{\text{ Potassium manganate }}{K _{2} MnO _{4}} +\underset{\text{Manganese dioxide }}{MnO_2}+ O _{2}$
