ABSTRACT

Densities and ultrasonic speeds of N-acetyl glycine in aqueous sucrose (0.05, 0.15, 0.25 and 0.35) mol kg-1 solutions have been measured as a function of molal concentration of N-acetyl glycine at temperatures (288.15, 293.15, 298.15, 303.15 and 308.15) K. Using the density and ultarsonic speed data, the partial molar volumes, transfer volumes, isentropic compression, partial molar isentropic compression, and transfer isentropic compression have been computed. Transfer parameters have been discussed in terms of solute-cosolute interactions on the basis of co-sphere overlap model. Partial molar expansibilities and interaction coefficients have also been calculated from these data. The results have been interpreted in terms of solute-solute and solute-solvent interactions in these systems. It is observed that there exist strong solute-solvent interactions in these systems, which increase with increase in temperature.
