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

`KMnO_4, K_2 MnO_4 and Cl_2`

B

`K_2 MnO_4, KMnO_4 and SO_2`

C

`K_3 MnO_4, K_2 MnO_4 and Cl_2`

D

`K_2MnO_4, KMnO_4 and Cl_2`

Text Solution

Verified by Experts

The correct Answer is:
A
`underset((X))(KMnO_4) overset(Delta) to underset((Y))(K_2MnO_4) + MnO_2 + O_ 2(g)`
`MnO_2 + 2NaCl + 2H_2SO_4 to MnSO_4 + Na_2 SO_4 + underset((Z))(Cl_2) + H_2O`
