Magneto-optical rotation studies of electrolyte solutions. Part 5.—Measurements on aqueous solutions of hydrophobic solutes

Abstract

The magneto-optical rotations of aqueous solutions of a number of hydrophobic electrolytes have been measured and compared with solutions of normal electrolytes, and the partial molal magnetic rotations of solute and solvent have been evaluated by a method previously described. The changes in the solvent partial molal rotation with concentration of solute have been interpreted in terms of the structure-forming and structure-breaking properties of the solutes on the solvent. The results parallel the n.m.r. findings of other workers and it is necessary to assume a different type of solvation for hydrophobic electrolytes than for normal electrolytes to explain the results.
