1. Types of electrochemical reactions

1.1 Reactions in homogeneous media

In the simplest case, the addition (reduction) or subtraction (oxidation) of electron(s) simply results in a change in the charge carried by the electroactive substance, without any change in its atomic composition (electrochemical system of simple charge transfer). These oxidations or reductions are represented by the simple reaction diagram : $Ox + n e^{-} ⇄_{(oxydation)}^{(réduction)} Red$
