The discussion centers around the standard reduction potential for the semireaction involving carbon dioxide and oxalate ion, specifically the reaction 2CO2 + 2e- <-> (C2O4)^2-. Participants seek to identify or calculate this potential, exploring various sources and methods.
Participants do not appear to reach a consensus on the standard reduction potential, as multiple values and methods are proposed without agreement on a definitive answer.
There are references to different sources and methods for calculating or identifying the standard reduction potential, indicating potential variability in values depending on the approach taken.
This discussion may be of interest to those studying electrochemistry, particularly in the context of standard reduction potentials and their calculations.
2CO2 + 2H+ + 2e- = H2C24 (electrode potential is -0.49V)Ann Par said:Good afternoon, i have been trying to find without success the standard reduction potential for the next semireaction:
2CO2 +2e- <-> (C2O4)^2-
Could someone please help me with that or tell me where could i find this potencial?. Thanks
