Abstract:
The electrochemical oxidation of halides and reduction of halogens have been studied in sulfolane, an aprotic solvent. Stable trihalide ions X 3 − are formed. The formation constants K of these X 3 − ions have been determined by potentiometry as 10 7.4 (X = I), 10 6.8 (X = Br), and 10 3 1 (X = Cl) in a 0.1 M LiClO 4 medium. The values of the constants K have also been obtained in methanol, a hydroxylic solvent, 10 4.2 (X = I), 10 2.3 (X = Br), and in mixtures of both solvents (X = I). The variations of solvation energies of X 3 − and X − ions from one solvent to the other were estimated by means of a ferrocene electrode.
