2. Change in acidity of the medium, formation of complexes and solid precipitates

Quantitative prediction of changes, based on the characteristics of the chemical systems involved, is easily accomplished when equilibrium relationships (electrochemical and chemical) can be applied, i.e., when all reactions are rapid (relative to the diffusion of the species involved). This is generally the case when studying the action of acids and bases, and of reagents forming complexes on electroactive substances, or on their electrolysis products. In this section 2 , the discussion is limited to cases of this nature, where only voltammograms in steady-state convective diffusion are considered (voltampereograms...
