Densities and viscosities of glycine, L-alanine, L-valine, L-threonine and L-arginine in aqueous solutions of (0.0, 0.1, 0.2, 0.3 and 0.4) mol center dot kg (1) L-ascorbic acid have been measured at T = (293.15, 303.15, 313.15 and 323.15) K under atmospheric pressure. The apparent molar volumes (V-phi), limiting partial molar volumes (V-phi(0)), limiting partial molar volumes of transfer (Delta V-tr(phi)0) and limiting partial molar expansibilities (E-2(0)) were computed by densities. The extended Jones-Dole equation was used to correlate the viscosities in order to obtain viscosity B-coefficients and the free energies of activation per mole of solvent (Delta mu(0 not equal)(1)) and solute (Delta mu(0 not equal)(2)) were also calculated. The contributions of zwitterionic end group (NH3+, COO), CH2 group, OH group and CNHNHNH2 group to V-phi(0) and viscosity B-coefficients were obtained through the group additivity analysis.
