Physicochemical Properties of L-Alanine in Aqueous Silver Sulphate Solutions at (298.15, 308.15, and 318.15) K

8 Apparent molar volumes (phi(V)) and viscosity B coefficients for L-alanine in (0.005, 0.010, 0.015, and 0.020) mol center dot dm(-3) aqueous silver sulphate (Ag2SO4) solutions were determined from the solution density and viscosity measurements at (298.15, 308.15, and 318.15) K as a function of amino acid concentration. The standard partial molar volumes (phi(0)(V)) and experimental slopes (S-V*) obtained from the Masson equation were interpreted in terms of solute-solvent and solute-solute interactions, respectively. To analyze solution viscosities in terms of viscosity B coefficients, the Jones-Dole equation was applied. The structure-making or -breaking ability of the amino acid has also been discussed in terms of the sign of (delta(2)phi(0)(V)/delta T-2)P. The activation parameters of viscous flow for the ternary solutions were also derived and explained in terms of transition state theory.
