The value of the standard emf of a cell in which molecular hydrogen under @S05921@ is oxidized to solvated protons at the left-hand electrode. Table of Standard Reduction Potentials . Cathode (Reduction) Half Reaction Standard Potential Eo (V) Li+ (aq) + e-→ Li (s) -3.0401 Cs+ (aq) + e-→ Cs (s) -3.026
The values of electrode potentials are customarily reported for the reduction processes (an arbitrary decision). The standard reduction potential for a metal electrode will be negative when referenced to the standard hydrogen electrode if the metal ion is more difficult to reduce than the hydrogen ion.

measured with a digital voltmeter. The Standard Electrode Potential (SEP) of any redox system is defined as the measured p.d. between the two electrodes of a cell in which the electrode of interest is measured relative to the SHE and in which all the chemical species contributing to the Table of Standard reduction potentials www.vaxasoftware.com Half reaction
Table 2. Selected Standard Reduction Potentials at 25 °C Assigning the potential of the standard hydrogen electrode (SHE) as zero volts allows the determination of standard reduction potentials, E°, for half-reactions in electrochemical cells. As the name implies, standard reduction potentials use standard states (1 bar or 1 atm for gases AP20 APPENDIX H Standard Reduction Potentials APPENDIX H Standard Reduction Potentials* Reaction E (volts) dE The temperature coefficient, dE /dT allows us to calculate the standard potential, E (T), at temperature T: E 1964 and 1971); G.
