ABSTRACT

Apparent molar volumes, V2,?, and viscosities, n, 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 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, obtained from V2,?, have been used to calculate the corresponding volume of transfer at infinite dilution, ?tV?, from water to aqueous sodium acetate solutions. B coefficients have been calculated using the Jones-Dole equation. The side-chain contributions to V?2 and B coefficients have been calculated. The comparison of ?tV? values with the literature shows that the effect of the acetate ion follows the same order as in the Hofmeister series.
