The voltage requirements of a membrane-divided cell are decreased by operating the cell with a catholyte temperature significantly in excess of the anolyte temperature, generally at least 10°C. greater and preferably at least 20°C. greater. The invention is particularly useful in an electrochemical acidification process whereby aqueous sodium chlorate and sodium sesquisulfate solution is acidified for use in a chlorine dioxide generating process and aqueous sodium hydroxide is produced as a by-product.
