ABSTRACT:
Herein disclosed are an electrochemical method for determining the end point of oxidation-reduction reactions, certain exchange reactions or precipitation reactions of organic or inorganic compounds and a dipole gold electrode used therein. The method comprises immersing a pair of electrodes or an electrode having a gold sensing portion and detecting and analyzing variations in electrical potential or current observed during the reaction. The electrode comprises a tube having a closed bottom, a pair of gold members passed through and projected outside the tube, a pair of terminals disposed at the top of the tube and a pair of metal elements electrically connecting the gold members and the terminals. This method and the electrode makes it possible to effectively determine the end point of the reaction with high accuracy and good reproducibility.
