Electrochemistry. Current-potential characteristics: theory (part 1)

However, a brief description of the essential features of the method is useful to justify the conditions under which it is implemented, so that the theoretical relationships we're going to demonstrate can be applied, if not rigorously, then at least within a range compatible with experimental error.

The general principle of voltammetry is to obtain a "response" of the electrode/electrolyte system under study – the value of the current flowing not only through the electrode, but also through the entire electrolysis circuit –, to the stress responsible for producing the electrochemical reaction(s), by scanning through the imposition and progressive variation of the electrode potential (potential sweep). The resulting figure, current intensity I (in A), or electrode current density j = I/A (in A · m ^-2 ), as a function of...
