Abstract

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 (φυ) of the amino acid is linearly related to its concentration in the two media. Apparent molar volume at infinite dilution (φυ) were estimated from least square fit of φυ 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-à-vis structure making or breaking effect of L-Alanine at the temperature under consideration.
