14 HNO3 + 2 MnCl2 + 7 PbO2 → 6 H2O + 2 Cl2 + 7 Pb(NO3)2 + 2 HMnO4
This is an oxidation-reduction (redox) reaction:
2 MnII - 10 e- → 2 MnVII (oxidation)
7 PbIV + 14 e- → 7 PbII (reduction)
4 Cl-I - 4 e- → 4 Cl0 (oxidation)
MnCl2 is a reducing agent, PbO2 is an oxidizing agent, MnCl2 is a reducing agent.
