SUMMARY
The standard reduction potential for the semireaction 2CO2 + 2e- <-> (C2O4)^2- is established at -0.64 V, as referenced from W.M. Latimer's oxidation potentials. To derive this value, one must calculate it using the Gibbs energies of formation for carbon dioxide and a 1M oxalate solution. An alternative electrode potential for the reaction 2CO2 + 2H+ + 2e- = H2C24 is noted at -0.49 V.
