Question

Which compound is oxidised and which compound is reduced? MNo2+4HCL-MnCL2+CL2+2H20

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 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
