Abstract
New measurements upon the respective solubilities of potassium acetate and benzoate at 25 °C in aqueous 1,4-dioxane and in aqueous tetrahydrofuran are reported, together with a quasi-thermodynamic development, from the union of chemical thermodynamics with the unrestricted result of theDebye-Hückel theory of electrolytes in solution, of a general theoretical function which in principle provides a summary descriptive expression of the relationship between the solibilities of any salt at any natural limiting concentrations and the polarities of its solvents.
Zusammenfassung
Neue Messungen der Löslichkeiten von K-Acetat und K-Benzoat in wäßrigen Lösungen von 1,4-Dioxan bzw. THF wurden durchgeführt. Es wird eine quasi-thermodynamische Behandlung der Daten mit einer Kombination von chemischer Thermodynamik und einer uneingeschränktenDebye-Hückel-Theorie der Elektrolyte in Lösung angewandt; diese theoretische Beschreibung liefert eine Beziehung zwischen der Löslichkeit eines Salzes und der Lösungs-mittelpolarität.
