The reactions between As(OH)3 and chloride ions are studied in different ionic media, at 25 degrees centigrades, by a standard potentiometric technique, based on the measurement of the potential of the redox couple As(V)/As(III) against a glass electrode. Low iodide concentrations were added to the test solution to obtain a rapid and reproducible potential. The formation of hydroxylated complexes was proved.

Abstract
The reactions between As(OH)3 and chloride ions are studied in different ionic media, at 25 degrees centigrades, by a standard potentiometric technique, based on the measurement of the potential of the redox couple As(V)/As(III) against a glass electrode. Low iodide concentrations were added to the test solution to obtain a rapid and reproducible potential. The formation of hydroxylated complexes was proved.File in questo prodotto:
