STUDY CHANGE IN THE ACID REGION NEAR THE ELECTRODE DURING THE ELECTROLYSIS OF AQUEOUS SOLUTIONS
The article presents the results of a study measuring the pH electrode areas (anolyte and catholyte) in the process of electrolysis of aqueous solution 0.1M K2SO4, as well as the three-way solution: 0.1M K2SO4 + 0,05M ZnSO4. As a result of research managed to obtain experimental confirmation of the change in pH electrode zones, dependence of the pH of the catholyte and anolyte of the electrolysis time, obtained theoretically expected and almost observed values of pH cathode and anode zones depending on the electrolysis time are in good agreement with each other. Research completed at the level consistent with the experimental numerical data obtained by electrochemistry laws. The findings suggest that in the operations of electrochemical technologies (electrosynthesis, copper plating, nickel plating) parallel to the oxidation or reduction of water on the electrodes can cause the pH deviation from the norm and lead to a violation of technological regime.
