Zeggeren F. Van,Benson G. C.

Abstract

The surface free energy for the interface between crystalline sodium chloride and a saturated alcoholic solution was determined from the solubility of sodium chloride in absolute ethyl alcohol as a function of the particle size of the salt. At 298°K. a value of 171 ergs/cm.2 was found. A general discussion of the validity of the Ostwald equation, which relates solubility and particle size, is presented.
