✦ Synopsis
In order to describe the adsorption of the Cl-ion at a mercury electrode in methanol and in ethanol more accurately, some additional properties of the inner layer were determined using Parsons' a-function data (collected in part I), the c&. values, and the thickness ratio parameters. The solvent effect on the specific adsorption of the Cl-ion was observed to be somewhat different in both aliphatic alcohols. It is discussed and compared with the results obtained for other ionic systems. R6sum6-Pour dtiie plus correctement l'adsorption spkifique des ions CI-sur une 6lectrode de mercure en methanole et en Whanole, on a determin6 quelques proprietees additionelles de la couche interieure I l'aide des donn&s resultant de la fonction 0 de Parsons (present&es en I-&e pat-tie), des valeurs de q& et des parametres du rapport des Bpaisseurs.

Zusammenfassung-Urn die Adsorption von den Cl--1onen am einer Quecksilberelelektrode in Ethanol und in Methanol genauer zu bcschreiben, bestimmte man einige neue Eigcnschaftcn von der inneren Schicht. Man benutzte dazu die Parsonssche Q, Funktion Daten (im I-ten Teil zusammengefasst), dieq&-Werte und das Dichtenverhiltnis. Der Einfluss von Liisungsmittel aufdie spezit%che Adsorption von Cl--1onen priifte in den beiden aliphatischen Alkoholen etwas unterschiedlich zu sein. Das wurde besprochen und mit den fur andere ionische Systeme erhaltenen Ergebnissen verglichen. PRRVIOUSLY,~~ a number of systematic studies on the specific adsorption phenomena at the mercury/solution interface in several non-aqueous solvents have been carried
