| Abstract: | The possibility of using electrodes made of a mixture of nonstoichiometric silver and copper(I) sulfides in the analysis of sulfur-containing aqueous solutions by direct potentiometry and potentiometric titration was assessed. The selectivity coefficients of the electrodes under study to chloride and iodide ions were determined. The effect of pH on the performance and conductivity of electrodes was studied. |
