The Effects of Impurities in the Electrolysis of Sodium Chloride Solution by Mercury Process

Abstract

This investigation deals with the effects of impurites in the electrolysis of sodium chloride solution by mercury process, especially a particular action of magnesium ions, and experimentally points out such an action and its mechanism in the following aspects. 1. Relations between the current and potential. 2. The eddy flow on the electrode surface. 3. Surface tension on the electrode. 4. Potential distribution. It was noticed by this investigation that the action of magnesium ions has a connection with the polarographic maximum in the relations between the current and potential, and also, reference was made to the cause of the appearance of the maximum phenomenon.
