Interfacial tensions electrolyte crystal-aqueous solution, from nucleation data

Abstract Homogeneous nucleation of sparingly soluble electrolytes was observed by means of a rapid flow technique. When the experimental values of the interfacial tensions are plotted as a function of the decadic logarithm of the solubilities the points are close to a straight line of slope, -0.02 J/m 2 . The intersection with the log solubility axis is at 1.6≙40 mol/1. These results support the theory that the hydration of ions and the wetting of the surface of an electrolyte crystal are very similar phenomena that can be described by the same interfacial tension.
