A new definition of electrolyte-solution acidity in the terms of Yeal" hydrogen-ion activity cn+r is proposed. The applicability of the Volta method for pun+? determinations and for the establishment of a universal acidity scale in HCl-H,O and HCOOH-Hz0 mixtures is shown.
nouvelle m6thode de determination de la teneur en acide des solutions Bectrolytiques en fonction de la valeur "r6elle" d'activite des ions d'hydrogene an+' est propos6e. En outre, l'on a montr6 la possibilite de l'application de la m6thode des diff&ences Volta de potentiel pour la mesure de la grandeur fir et pour l'etablissement d'une echelle universelle de teneur en acide clans les m6langes HCl-H,O et HCOOH-HaO. Zusammenfass~-Eine neue Definition der Aziditiit von Elektrolytliisungen durch die Werte der "reellen" Wasserstoffionenaktivitiit an+" wird vorgeschlagen. Die Anwendbarkeit der Methode der VoltapotentialdifferMessung zur Ermittlung der pa, r-Werte und Bildung der universellen Azidititskala in HCl-HI0 und HCOOH-H,O-Mischungen wird gezeigt.
