Question

Define oxidation and reduction. In the following
reactions, identify which one is reduced and which
one is oxidized?
MnO2 + 4HCI MnCl2 + 2H2O + CI2​

Answer 1

Answer:

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
