The densities and refractive indices were determined at 25° for solutions of the halides of some of the alkali metals, over a concentration range from 0.1 molal to almost saturation. The partial molal volumes were calculated by differentiating the equations of the volume-molality curves. From the refractive index the specific refractivity of the solution and of the solute were calculated. The specific refractivity of the solute was found to be constant throughout the concentrations studied. Using an equation derived by Hückel, involving the refractive index, the dielectric constants of the solutions were calculated.
