Journal Title:Journal of Chemical, Biological and physical sciences

Densities (r) and speeds of sound (u) of ternary mixtures of toluene-4-sulfonic acid in 70 % (v/v) acetonewater and 70% (v/v) ethanol-water mixtures for different concentrations of sulfonic acid were measured at 300 K. Apparent molar volume (fv) and adiabatic compressibility (Ks) of solutions were determined from the measured densities and sound velocities of solutions and solvent mixtures. The limiting infinite dilution apparent molar volume (f0 v) was evaluated from the Massons relation. Data has been discussed in terms of ion-ion and ion-solvent interactions.
