| Résumé : | FORMAMIDE is a very good solvent for many strong and medium weak acids. In order to determine their dissociation constants accurately by potentiometric measurements it is necessary to know the standard potential of a reference electrode with respect to the normal hydrogen electrode. Until recently, only the value of the cadmium-cadmium chloride electrode has been given in the literature 1. We have been able to determine the standard potential of the silver-silver chloride electrode by the classical method using the following cell without liquid-liquid junction: Pt, H 2/HCl(HCONH 2)/AgCl, Ag Platinum electrodes were prepared according to Jones 2 and the silver-silver chloride electrodes by the electrolytic method 3,4. (Both types of electrodes were reproducible within 0.5 mV.) © 1958 Nature Publishing Group. |
