21. The reference electrode has a known reduction potential . 22. FAD has a more positive reduction potential than NAD + and is a very strong oxidizing agent. 23. Phosphines are completely absent from living systems and do not reduce disulfide bonds despite mild reduction potential . 24. Like pH, the reduction potential represents how strongly electrons are transferred to or from species in solution. 25. When comparing the reduction potentials in reactions 2 and 4, the reduction of chloride ion is favored. 26. Thus, the oxidation potential of a chemical species is listed as the reduction potential of its oxidized form. 27. :Standard reduction potential is the reduction potential at 25 o C, 1M concentration of both anion and cation. 28. :Standard reduction potential is the reduction potential at 25 o C, 1M concentration of both anion and cation. 29. Sometimes pE is used as a unit of reduction potential instead of Eh, for example in environmental chemistry. 30. It is the reduction potential of each species present that will determine which species will be oxidized or reduced.
