WebFeb 9, 2024 · In soil, methanogenesis occurs almost exclusively in a flooded condition due to its reduction potential being so low (below 100 mV). The use of CO 2 in this fashion yields much less energy than the reactions of previous electron acceptors, so this process has lower growth rates in turn. WebJun 23, 2024 · The anion with the lowest reduction potential will be oxidised at the anode where oxidation takes place. As a result, OH-, which has a standard reduction potential of 0.40 volt, will be oxidised first, followed by Cl-, which has a standard reduction potential of 1.36 volt.
