ABSTRACT

Densities and viscosities of aqueous solutions and 1.0 mol*kg 1 aqueous urea solutions of glucose, fructose, sucrose, and lactose have been measured at two different temperatures [(308.15 and 318.15) K] in the concentration range (0 to 3) mol*kg 1. The different derived parameters such as the apparent molal volume of solute (V) and Jones Dole equation viscosity B- and D-coefficients have been obtained for these binary and ternary mixtures. Partial molal volumes (V-20) at infinite dilution were obtained by smooth extrapolation of the V m curves to zero concentration. These data were used to obtain the corresponding volume of transfer (?transV-20) for saccharides from pure water to 1.0 mol*kg 1 aqueous urea solutions at two different temperatures. The results are interpreted in terms of various interactions among solute and solvent molecules.
