Standard Electrode Potentials

H2O2 contains oxygen in a state of oxidation midway between molecular oxygen and water.

Oxygen Moiety Reduction →
O2 ↔ H2O2 ↔ H2O
Oxygen Valence
0 -1 -2
← Oxidation

 

H2O2 → O2 + 2H+ + 2e- Eo = -0.682 V
H2O2 + 2H+ + 2e- → 2H2O Eo = 1.776 V

 

For perhydroxyl ion (HO2-):

OH- + HO2- → O2 + H2O + 2e- EBo = 0.084 V
3OH- → HO2- + H2O + 2e- EBo = -0.87 V
