Thermo-physical Properties of L-Arginine in aqueous and aqueous NaCl Solutions at Different Temperatures

Abstract

Density and viscosity data for L-Arginine (L-Arginine + NaCl + water) systems were determined at 288.15 K and 298.15 K. The density data has been utilized to calculate apparent molar volume, limiting apparent molar volume, partial molar volume of transfer and limiting apparent molar expansivity. The viscosity data have been used to calculate coefficient of viscosity, relative viscosity and B coefficients. These thermophysical properties are used in understanding the interactions between solute-solvent and structure making or breaking ability of the solute.
