Abstract :

The physicochemical properties of solute in solutions provide valuable information on solute solvent, solute solute and solvent solvent interactions. The intermolecular forces between theliquids molecules and solvent molecules affect the viscosity of the solution. Information regardinginter and intra molecular interactions can be obtained from volumetric, and viscometric data in asolute solvent system. This study reports the volumetric and viscometric properties of solution of :-alanine at the concentration range of 0.05 - 0.5 mol dm-3 in water and liquid ammonia at temperaturerange of 293 - 313K. Apparent molar volume at infinite dilution ( ov
) was estimated from the leastsquare fit of v
vs concentration. Viscosity coefficients A and B were calculated from the viscositydata JonesDole equation. Viscosity coefficients A and B were calculated from the viscosity dataJonesDole equation. The activation parameters for viscous flow #1#2#μ1 ,μ ,S and #1 H werealso estimated using Eyring equation. The data are explained vis-à-vis structure making or breakingeffect of : - Alanine in the solvents under conditions of investigation.
