Abstract
The present paper is concerned with the electrolysis of sodium chloride solution by means of double membrane which is made for this particular purpose by combining cation selective membrane and anion selective membrane.
The result of the research can be summarized as follows;
1) The hydrolyzing efficiency decrease in proportion to the decrease of current density, and to the in crease of the concentration of sodium chloride solution.
2) The current efficiency decreases in proportion to the duration of electrolysis.
3) The change of temperature has very little influence upon the hydrolyzing efficiency.
Special consideration was given to the study of the diffusion of sodium chloride and hydrochloric acid into each of the membranes, so that the change of hydrolyzing efficiency could be discussed and elucidated.
