Refractive indices of saturated solutions were measured and solubilities obtained using a calibration curve. Attainment of equilibrium verified by making repetitive measurements after several additional days. The International Union of Pure and Applied Chemistry Heric, E. L.; Posey, C. D.; J. Chem. Eng.
