Kinetics of the Sodium Chlorate Formation in Electrolysis of Chloride Solutions with Use of Dimensionally Stable Anodes

The kinetics of the formation of sodium chlorate during electrolysis of chloride solutions with use of dimensionally stable anodes is studied. An analysis and calculations suggest that the experimental results are well described by the proposed set of differential equations under the assumption that the homogeneous chemical reaction of chlorate formation has second, rather than third, order by active chlorine.
