摘要
Apparent molar volumes (phi(V) ) and viscosity B-coefficients for glycine in 0.005, 0.010, 0.015, and 0.020 mol. dm(-3) aqueous silver sulphate (Ag(2)SO(4)) solutions have been determined from solution density and viscosity measurements at (298.15, 308.15, and 318.15) K as a function of glycine concentration. The standard partial molar volume (phi(0)(V)) and experimental slopes (S(V)*) obtained from the Masson equation have been interpreted in terms of solute-solvent and solute-solute interactions, respectively. The viscosity data were analyzed using the Jones-Dole equation, and the derived parameters A and B were interpreted in terms of solute-solute and solute-solvent interactions, respectively. The standard volumes of transfer (Delta phi(0)(V)) and viscosity B-coefficients of transfer (Delta B) of glycine from water to aqueous Ag(2)SO(4) solutions were derived to study various interactions in the ternary solutions. The structure making or breaking ability of glycine has 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 calculated and explained in terms of transition state theory.
