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.
