Oxidation/Reduction Limits for H2O Consider the Oxidation of H2O to yield O2(g), the half reaction can be written as; 2 H2O === O2(g) + 4 H + + 4 e-Eo = -1.23 V (from tables) Re-writing this as a reduction (by convention) and dividing by 4 (for convenience) yields; ¼ O2(g) + H + + e-==== ½ H 2O E o = 1.23 V (note the sign change in Eo, but the magnitude remains unchanged) Therefore, it takes 475 kJ of energy to make one mole of O2 as calculated by thermodynamics.
