Valuable information regarding solute solvent, solute solute and solvent solvent interactions are obtainable from volumetric, viscometric and other thermodynamic data in a solute solvent system. Consequently we study the density and viscosity of L-Alanine in aqueous and ethanol media as a function of concentration at the temperature ranges between 293 and 313 K. The apparent molar volume (Ï†Ï…
) of the amino acid is linearly related to its concentration in the two media. Apparent molar volume at infinite dilution (Ï†Ï…
) were estimated from least square fit of Ï†Ï…
vs molarity. Viscosity coefficients A and B were calculated from the viscosity data Jones-Dole equation. The activation parameters for viscous flow
were also estimated using Eyring equation. The data are explained vis-Ã -vis structure making or breaking effect of L-Alanine at the temperature under consideration.
