WebAnd this voltage is the Standard Cell Potential. So E naught of the cell is equal to positive 1.10 volts. And the Standard Cell Potential depends on the potentials for the two half reactions that make up the cell. So if we know the potentials for the half reactions that make up the cell, we can calculate the standard potential of any galvanic cell. WebThe electric potential also varies with temperature, concentration and pressure. Since the oxidation potential of a half-reaction is the negative of the reduction potential in a redox reaction, it is sufficient to calculate either one of the potentials. Therefore, standard electrode potential is commonly written as standard reduction potential.

WebMay 17, 2015 · The sign on the potential determines the direction in which electricity flows. By convention, a galvanic cell (spontaneous reaction) has a positive E°, while an electrolytic cell (non-spontaneous reaction) has a -E°. The magnitude of the potential stays the same, but a sign is added to signify the direction of current flow.
