CHARACTERISTICS OF APPLICATION OF QUASI-EQUILIBRIUM THIN-LAYER COULOVOLTAMMETRY TO STUDY PROTON-DEPENDENT REDOX REACTIONS IN UNBUFFERED ELECTROLYTES

Characteristics of the application of quasi-equilibrium thin-layer cou lovoltammetry to analyze proton-dependent redox reactions in solutions not containing buffer reagents are considered. An expression is obtai ned for the differential chemical capacity of a system as a function o f the potential determined by a series of discrete steps of small ampl itude. The effect of buffer capacity, the relation between reactant co ncentration and the initial acidity of the medium, and the acid-base p roperties of the reaction partners on the form of the quasi-equilibriu m coulovoltammetric curves is considered.
