Chronopotentiometry of solutions containing sodium iodide and iodine in dimethylsulphoxide

Chronopotentiometric waves of solutions of sodium iodide, and sodium iodide with added iodine in dimethylsulphoxide, were determined on platinum electrodes. Sodium perchlorate was used as supporting electrolyte. The concentration range was from 2 × 10<sup>−3</sup> to 4 × 10<sup>−2&...

description	Chronopotentiometric waves of solutions of sodium iodide, and sodium iodide with added iodine in dimethylsulphoxide, were determined on platinum electrodes. Sodium perchlorate was used as supporting electrolyte. The concentration range was from 2 × 10<sup>−3</sup> to 4 × 10<sup>−2</sup> M and the temperature from 25·0 to 45·0°C. The anodic waves exhibit two well-defined steps characterized by definite transition times, while only one step is observed for the cathodic waves given by the solutions with added iodine. The cathodic waves are irreversible. The first anodic wave shows a larger irreversibility than the second. The results are discussed in comparison with previous information gathered for the same systems by employing a platinum rotating disk electrode. Diffusion coefficients for tri-iodide and iodide ions in solutions of DMSO obtained from chronopotentiometry are in agreement with those earlier reported derived from the rotating disk electrode.
