Description

If two similar half-cells which differ only in the concentration c of their electrolyte solutions are combined, then a potential difference also forms between those half-cells. The general relationship is described in the Nernst equation:

The potential E therefore depends on the temperature in Kelvin T and on the proportionality factor R, the universal gas constant. Other parameters which play a role include the ion valence n and the Faraday constant F. The dependence on concentration and temperature are investigated in experiment C4.4.3.4.
