Standard Electrode Potential Definition Under standard conditions, the standard electrode potential occurs in an electrochemical cell say the temperature = 298K, pressure = 1atm, concentration = 1M. The symbol 'E ocell ' represents the standard electrode potential of a cell. Significance of Standard Electrode Potential This table is an alphabetical listing of common reduction half-reactions and their standard reduction potential, E 0, at 25 C, and 1 atmosphere of pressure. The standard reduction potentials are all based on the standard hydrogen electrode.Standard oxidation potentials can be calculated by reversing the half-reactions and changing the sign of the standard reduction potential Applying this logic to the numerically ordered listing of standard electrode potentials in Table 17.1 shows this listing to be likewise in order of the oxidizing strength of the half-reaction's reactant species, decreasing from strongest oxidant (most positive E°) to weakest oxidant (most negative E°) We can do that by looking at our table here. So -.76 is the standard reduction potential. Since we reversed our half-reaction, we just need to change the sign. The oxidation potential must be +.76. All we need to do is reverse the sign to get our standard oxidation potential, so we get +.76
