The osmotic coefficients of aqueous CsCl, SrCl/sub 2/, and mixtures of NaCl and CsCl have been measured at 25/sup 0/C by the isoplestic method. The solubilities of CsCl and SrCl/sub 2/-6H/sub 2/O have also been measured at this temperature. These experimental data are compared with other available activity and solubility data and are in good agreement in most cases. Least-squares equations were used to represent the single-salt osmotic coefficients, and these equations were used to calculate water activities and mean molal activity coefficients. Data for the NaCl-CsCl solutions are accurately represented by the two-parameter form of Pitzer's equations. 2 figures, 6 tables.
