Theoretical aspects of the indirect redox potentiometric method for determination of oxidizers and reducers without titration

Abstract

The theoretical analysis of the redox potentiometry of reducers and oxidizers is carried out, which involves the electrochemical characteristics of generalized analytical reactions and the development of simplified equations for calculating the sought concentration and the sensitivity of the method. The use of degrees of oxidation of atoms made it possible to elucidate the reaction stoichiometry and determine which atoms in complex compounds are involved in the electron transfer. The terminology of the redox potentiometric method is improved.
