ABSTRACT

Densities, q, and speed of sound, u for trisodium citrate and tripotassium citrate in (0.085 and 0.18) mol kg 1 aqueous solutions of N-acetyl glycine at T = (288.15, 293.15, 298.15, and 303.15) K have been measured. The different parameters such as apparent molar volume, limiting apparent molar volume, transfer volume, partial molar expansibility have been derived from density data. Experimental values of the speed of sound were used to estimate apparent molar adiabatic compressibility, limiting apparent molar adiabatic compressibility, and transfer parameter. The pair and triplet interaction coefficient have been calculated from transfer parameters. These parameters have been discussed in the light of ion ion and ion solvent interactions
