Look up the reduction potential, E o reduction, for the reduction half-reaction in a table of reduction potentials; Look up the reduction potential for the reverse of the oxidation half-reaction and reverse the sign to obtain the oxidation potential. The standard reduction cell potential and the standard oxidation cell potential can be combined to determine the overall Cell Potentials of a galvanic cell. The equations that relate these three potentials are shown below: 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. The standard cell potential is positive, so the reaction is spontaneous as written.

These are typically recorded in tables of standard reduction potentials. For an oxidation half reaction, the oxidation potential is mutiplied by -1 to go to the reduction potential. The Nernst Equation and Electrochemical Potential. In electrochemistry, the Nernst equation can be used, in conjunction with other information, to determine the equilibrium reduction potential of a half-cell. It can also be used to determine the total voltage, or electromotive force, for a full electrochemical cell.
