Question

Identify the oxidising agent, reducing agent, substance oxidised and
substance reduced in the following reactions.
MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O

Answer 1

Thank you for getting in touch with us for the answer of your query. In the reaction MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O , Cl (chlorine) is the substance which is oxidized from the HCl, and it is the reducing agent for the MnO2 as well. As Cl is the oxidized substance in HCl, thus it is the oxidizing agent in the reaction. I hope this makes sense to you and this answer will be helpful for you.

Answer 2

MnO2 is reduced and HCl is oxidised
