Question

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

Answer 1

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 theMnO2 as well. as Cl is the oxidizedsubstance in HCl, thus it is theoxidizing agent in the reaction
