The impedance of the interface mercury/electrolyte-solution has been measured for NaClO,, NaNOs, Na, SO~, NaCl and NaI solutions when the interface is exposed to gamma rays. In all cases radiation led to a decrease in the differential capacitance, most probably through the formation of films of stab

β¦ Synopsis
The resistive and capacitative components of impedances at metal/solid, metal/molten-salt and metal/aqueous-solution interfaces normally vary inversely as some power of the ac frequency. Reasons are advanced for a generalized treatment of the problem rather than the separated approaches of Jaffk and succeeding workers for solids, and Grahame and others for electrolytes. Some data for metal/molten-salt impedances are examined by both the above methods.
RBsum&Les composantes rtsistives etcapacitives des impedances interfaciales m&al/solide, m&al/se1 fondu, m&tal/solution aqueuse, varient ordinairement selon l'inverse d'une certaine puissance de la frCquence du courant altematif. Un traitement gCnCra1 de cette question est pr&f&? aux mCthodes distinctes d'approche de Jaffb pour les solides et de Grahame pour les Electrolytes. Quelques r6sultats obtenus avec des interfaces m&al/se1 fondu sont interpr&Cs selon chacun de ces pro&d&s.
Zusammenfassung-Beide
Komponenten der Impedanz an Phasengrenzen Metall/Fest, Metall/ geschmolzenes Salz und Metall/wZisserige LGsung sind normalerweise umgekehrt proportional einer Potenz der Wechselstromfrequenz.
Es werden Griinde fur eine verallgemeinerte Behandlung des Problems angefiihrt. Diese allgemeine Behandlung ist vorteilhafter als die speziellen Betrachtungsweisen welche Jaff& und spatere Autoren fi.lr feste Phasengrenzen bzw. Grahame und andere fiir Elektrolyte entwickelt haben. Einige Messwerte der Impedanz an Phasengrenzen Metall/geschmolzenes Salz werden unter Heranziehung der beiden erwPhnten Methoden diskutiert .
