Electrode Reactions and Galvani Potential Differences

Abstract

Initially, the terms Galvani potential for the electric potential in the bulk of a phase, electrochemical potential μ˜$$ \tilde{\mu} $$, and electron potential μe are introduced to characterize processes in which charge-carrying species are involved. The electrochemical potentials can be used to determine the Galvani potential difference between two phases in equilibrium, as an especially simple example between two different metals. The formation of an electric double layer at the interface of both metals as well as the corresponding Galvani potential difference, the
