Abstract

Density and viscosity measurements were performed for amino acids in 0.05-0.25 M aqueous sucrose at 293.15, 303.15 and 313.15 K. The measured values of density and viscosity in a ternary system were used to determine some important parameters, such as the partial molar volume, the transfer partial molar volume, partial molar volume expansibility, viscosity B-coefficient, variation of B with temperature dB/dT and free energy of activation. The results were interpreted in terms of solute-solute and solute-solvent interactions and structure making/breaking ability of solutes in aqueous sucrose solution.
