Vedclass · Answer

(B) The given reaction sequence is as follows:$1$. Pyrolusite is $MnO_2$,which is $(A)$.$2$. When $MnO_2$ is fused with $KOH$ in the presence of air,it forms potassium manganate $(K_2MnO_4)$,which is a green compound $(B)$.$2MnO_2 + 4KOH + O_2 \rightarrow 2K_2MnO_4 + 2H_2O$$3$. Potassium manganate $(K_2MnO_4)$ on reaction with $H_2SO_4$ (acidic medium) disproportionates to form potassium permanganate $(KMnO_4)$,which is a purple crystal $(C)$.$3K_2MnO_4 + 2H_2SO_4 \rightarrow 2KMnO_4 + MnO_2 + 2K_2SO_4 + 2H_2O$Therefore,$(A) = MnO_2$,$(B) = K_2MnO_4$,and $(C) = KMnO_4$.

Identify $(A)$,$(B)$ and $(C)$ in the given reaction sequence:
