Calculating the Cell Potential: T he net reaction of a voltaic cell constructed from a standard zinc electrode and a standard copper electrode is obtained by adding the two half-reactions together:

( reference ) There are several potential bench marks in common use, but the most ancient is the half-cell in which hydrogen gas is bubbled over a platinum electrode immersed in a solution having a known concentration of hydrogen ions. The cell potential in Chapter 17.2 Galvanic Cells (+0.46 V) results from the difference in the electrical potentials for each electrode. While it is impossible to determine the electrical potential of a single electrode, we can assign an electrode the value of zero and then use it as a reference. In electrochemistry, a half-cell is a structure that contains a conductive electrode and a surrounding conductive electrolyte separated by a naturally occurring Helmholtz double layer.

Den uppmätta potentialskillnaden mellan två där Ecathode och Eanode är potentialen för två olika halvor Som för andra termodynamiska mängder är standardcellspotentialen, E ° -cellen, en cellpotential The cell potential, Ecell, is the measure of the potential difference between two half cells in an electrochemical cell. The potential difference is caused by the ability of electrons to flow from one half cell to the other. Electrons are able to move between electrodes because the chemical reaction is a redox reaction. Cell potential may refer to: . Electrode potential; Membrane potential, the potential across the membrane of a biological cell; Standard electrode potential The cell potential must be positive in order for redox reaction of the cell to be spontaneous in the reverse direction.
