AB - Anolyte composition in mercury cells for chlorine‐caustic electrolysis is calculated as a function of pH. and the relation between anodic current loss and the anolyte pH is derived. Reactions between anodic and cathodic by‐products and dependence of the cathodic current loss upon the anolyte pH are also discussed. Finally, certain components of the feed brine which affect pH of the anolyte are examined. It is demonstrated that optimum current efficiency with respect to both chlorine and caustic cannot be reached if pH of the anolyte is greater than 3, that stirring the cathode film, e.g., by solid particles on the mercury surface, decreases current efficiency, and that alkalinity of the feed brine, which must not exceed a certain value, is made up of the follow ing concentrations: .
