FREEZING POINT DEPRESSIONS IN SODIUM FLUORIDE. II. EFFECT OF TETRAVALENT FLUORIDES
Journal Article
·
· Journal of Physical Chemistry
The freezing point depressions in NaF caused by ZrF₄, HfF₄, ThF₄, and UF₄ were measured and the excess partial molal free energies of solution of NaF calculated therefrom. All the deviations from ideal solution behavior were negative and greater than these for alkaline earth fluoride solutes. It was found that the deviations increase with the tetravalent cation radius, and this fact is ascribed to steric effects. The freezing point of NaF containing two solutes was also studied, and a synergistic effect was found for solute concentrations of 15 mole %. (D.L.C.)
