Studien zum Vorgang der Wasserstoffübertragung, 63. Elektrochemische Herstellung einiger Amalgame und Bestimmung ihrer Potentiale/ Studies on the Occurrence of Hydrogen Transfer, 63. Electrochemical Preparation of Some Amalgams and Measurement of the Potentials

Abstract

Abstract The amalgams of lithium, sodium, potassium, barium and zinc were prepared electrochemically (potentiostatic and galvanostatic, see Tables I and II). The potentials of these were measured in acetonitrile, THF and DMF, using the corresponding Perchlorate (Li, Na, K, Ba, Zn) or tetrabutylammonium perchlorate as electrolyte and a standard calomel olektrode (SCE) (Table III). In the case of the lithium amalgam, the dependence of the potential on the lithium content was studied (Table IV). The potential moves slightly to more positive values on dilution, dilution by a factor of 100 producing a shift of only ca. 100 mV.
