Abstract

Standard potentials of the couples S<sub>2</sub>O<sub>8</sub><sup>2–</sup>/SO<sub>4</sub><sup>2–</sup> and S<sub>2</sub>O<sub>8</sub><sup>2–</sup>/HSO<sub>4</sub><sup>–</sup> in the temperature range 0–50 °C and reversible anodic potentials of the electrosynthesis of peroxodisulfates at various initial concentrations of M<sub>2</sub>SO<sub>4</sub> and H<sub>2</sub>SO<sub>4</sub>, various conversion degree of sulfate to peroxodisulfate in the same temperature range under neglecting the effect of activity coefficients of reaction components have been derived. Reversible anodic potentials of the electrosynthesis of almost saturated solutions of ammonium peroxodisulfate in the temperature range 10–40 °C under various reaction conditions have been calculated on taking into account the corresponding activity coefficients. It has been shown that the reversible anodic potentials under respecting activity coefficients of reaction components are by about 20–30 mV higher. The results of this contribution can be applied to all chemical or electrochemical reactions of peroxodisulfates.
