Apparent molar volumes, V-2,V-phi,V- and viscosities, eta, of glycine, DL-alpha-alanine, DL-alpha-amino-n-butyric acid, L-leucine, and L-phenylalanine in water and in (0.5, 1.0, 2.0, 4.0, and 5.5) mol(.)kg(-1) aqueous sodium acetate solutions have been determined at 298.15 K from densities and flow time measurements, respectively. The standard partial molar volumes, V-2(infinity), obtained from V-2,V-phi, have been used to calculate the corresponding volume of transfer at infinite dilution, Delta(t)V(infinity), from water to aqueous sodium acetate solutions. B coefficients have been calculated using the Jones-Dole equation. The side-chain contributions to V-2(infinity) and B coefficients have been calculated. The comparison of Delta(t)V(infinity) values with the literature shows that the effect of the acetate ion follows the same order as in the Hofmeister series.
