Results of isopiestic measurements at 25/sup 0/C for aqueous solutions of sodium p-toluenesulfonate, sodium 2,4-dimethylbenzenesulfonate, sodium 2-methyl-5-isopropylbenzenesulfonate (sodium p-cymenesulfonate), and sodium 2,5-diisopropylbenzenesulfonate are reported. Values of the osmotic coefficients decline more rapidly with increasing molality for compounds of higher alkyl substitution. Activity coefficients were computed from least-squares fits to the water activities.
