An Intiative by Sri Chaitanya

$X = black, {MnO}_{2} Y = green, K_{2} {MnO}_{4}, Z = {KMnO}_{4}$

$X = green, {Cr}_{2} O_{3}, Y = Yellow, K_{2} {CrO}_{4}, Z = K_{2} {Cr}_{2} O_{7}$

$X = black, {MnO}_{2}, Y = Blue, K_{2} {CrO}_{4}, Z = {KMnO}_{4}$

$X = black, {Bi}_{2} O_{3}, Y = colourless {KBiO}_{2}, Z = {KBiO}_{3}$

answer is C.

Detailed Solution

$\underset{X (black)}{2 {MnO}_{2}} + 2 K_{2} {CO}_{3} + \underset{air}{O_{2}} \overset{∆}{\to} \underset{Green (Y)}{2 K_{2} {MnO}_{4}} + 2 {CO}_{2}$

$\underset{Y}{2 K_{2} {MnO}_{4}} + {Cl}_{2} \to \underset{Z (pink)}{2 {KMnO}_{4}} + 2 KCl$
