Question

MnO2 + 4HCl → MnCl2 + 2H2O + Cl2
The reaction given above is a redox reaction because in this case:

• A. MnO2 is oxidised and HCl is reduced.
• B. HCl is oxidised.
• C. MnO2 is reduced.
• D. MnO2 is reduced and HCl is oxidised.

Answer 1

Answer: (D)

MnO2 is reduced and HCl is oxidised.

Answer 2

In the given reaction,$MnO_2$ is reduced to $MnCl_2$, losing oxygen atoms, while HCl is oxidized to $Cl_2$, losing hydrogen atoms.
