Vedclass · Answer

(C) The industrial preparation of potassium permanganate $(KMnO_4)$ involves the following steps:$1$. Fusion of pyrolusite ore $(MnO_2)$ with $KOH$ in the presence of air $(O_2)$ to form potassium manganate $(K_2MnO_4)$:$2MnO_2 + 4KOH + O_2 	o 2K_2MnO_4 + 2H_2O$Here,$X = MnO_2$ and $Y = K_2MnO_4$.$2$. The green potassium manganate $(K_2MnO_4)$ is then subjected to acidic disproportionation to form potassium permanganate $(KMnO_4)$:$3K_2MnO_4 + 2H_2SO_4 	o 2KMnO_4 + MnO_2 + 2K_2SO_4 + 2H_2O$Here,$Z = KMnO_4$.Thus,$X = MnO_2, Y = K_2MnO_4, Z = KMnO_4$.
