(X) + K_2CO_3 + Air overset(heat)rarr (Y) (Y)+Cl_2 rarr (Z) Pink which of the following is correct ?

Answer»

X back , `MnO_2`Y = BLUE, `K_2CrO_4,Z=KMnO_4`
X=green `Cr_2O_3` Y=yellow `K_2CrO_4, Z K_2CrO_7`
X=black ,`MnO_2` Y= green `K_2MnO_4, Z=KMnO_4`
X = black , `Bi_2O_3,`Y = COLOULESS `KBiO_2,Z = KBiO_2`

SOLUTION :`MnO_(2) + K_2CO_3 + "AIR" overset(Delta) rarr K_2MnO_4, K_2MnO_4 + Cl_2 rarr KMnO_4`
