Apparent molar volumes of electrolytes. Part 4.—KCl in formamide at 25°C
Abstract
Apparent molar volumes of KCl in formamide in the concentration range 0.005–1.0 M at 25°C have been measured using a magnetically-operated dilatometer. The Debye-Hückel appa rent molar volume limiting slope for 1-1 electrolytes in formamide at 25°C has been calculated to be 1.104 ml mol– l.½ This value is satisfactorily approached experimentally with KCl in very dilute formamide solutions.
