Galvani potential

In electrochemistry is meant by galvanic voltage ( also the inner electrical potential difference ) of the inner electrical potential difference between two phases. The Galvani potential of a phase is to sogrößer, the higher the tendency of the particles is donating electrons.

One example of the electroplating voltage is the difference between the inner electric potential of an electrode (a fixed conductor ) and the inner electric potential of an electrolyte (liquid). Innereres potential indicates in this case that the potential is meant a point in the phase, not in the vicinity of a phase transition.

Together with the known as the Volta potential difference of external electrical potentials results in the total potential difference between two phases. The outer electrical potential is due to the excess charges of opposite sign at the phase boundaries.

The different types of potential differences play a role in the exact treatment of galvanic cells.

The name goes back to the Italian physician Luigi Galvani.

The Galvani voltage is in principle measurable only between phases of the same composition.
