| Abstract: | The review is dedicated to theory and experimental applications of polarography for studies of consecutive and parallel chemical reactions preceding electron transfer and occurring in the bulk or surface (adsorption) reaction layers. The methodology of finding kinetic and equilibrium parameters including formal potentials is presented. The following chemical reactions are considered: (1) protonation of anions of benzene polycarboxylic acids; (2) dehydration (decyclization) and protonation of carbonyl compounds; (3) proton exchange between mixed solvent molecules; (4) formaldehyde-amine interaction; (5) complexation with the ligand catalyzing electroreduction of metal ions; (6) dissociation of metal complexes; (7) formation of deposits of metal hydroxides with parallel oxygen reduction. |
