ABSTRACT
Apparent molar volumes (.V ) and viscosity B coefficients for l-alanine in (0.005, 0.010, 0.015, and 0.020) mol E dm.3 aqueous silver sulphate (Ag2SO4) solutions were determined from the solution density and viscosity measurements at (298.15, 308.15, and 318.15)Kas a function of amino acid concentration. The standard partial molar volumes (.0V ) 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 ( A2.0V/ AT 2)P. The activation parameters of viscous flow for the ternary solutions were also derived and explained in terms of transition state theory.
