प्रश्न
State whether the given chemical reaction is a redox reaction or not. Justify your answer.
\[\ce{MnO_2 + 4HCl->MnCl_2 +2H_2O + Cl_2}\]
उत्तर
The given reaction is an example of an oxidation-reduction reaction or redox reaction.
A substance is oxidised when it receives or loses hydrogen during a process. A material is decreased when it loses oxygen or absorbs hydrogen during a process. HCl loses hydrogen in the proposed process to generate Cl2. The provided reaction is thus a redox reaction.
