MnO 2 +4HCl⟶MnCl 2 +2H 2 O+Cl 2
Oxidation state: +4 −1 +2 0
Increase in oxidation state = Oxidation ⇒
As chlorine increases from −1⟶0⇒ (Oxidation of HCl)
Decrease in oxidation state = Reduction ⇒ As manganese decreases from +4→+2⇒ (Reduction of MnO 2 )⇒MnO 2
is reduced, HCl is oxidized, MnO 2
is oxidizing agent, HCl is reducing agent.
