Thermal decomposition of a Mn compound (...

Thermal decomposition of a Mn compound (X) at 513 K results in compound Y, `MnO_(2)` and a gaseous product. `MnO_(2)` reacts with NaCl and concentrated `H_(2)SO_(4)` to give a pungent gas Z. X, Y and Z respectively, are :

A

`K_2MnO_4, KMnO_4 ` and `SO_2`

B

`K_2MnO_4 , KMnO_4` and `Cl_2`

C

`K_3MnO_4, K_2MnO_4` and `Cl_2`

D

`KMnO_4, K_2MnO_4` and `Cl_2`

Text Solution

Verified by Experts

The correct Answer is:
D
`KMnO_4, K_2MnO_4` and `Cl_2`
