Ultrasonic Studies of Amino Acids in Aqueous Sucrose Solution at Different Temperatures


The density (ρ), viscosity (η) and ultrasonic velocity (U) were measured for L-histidine, L-arginine and L-lysine in aqueous sucrose (0.5 M) solution at 298, 303 and 308 K. Using the experimental values, the adiabatic compressibility (β), hydration number (nH), apparent molal compressibility (φK), apparent molal volume (φV), limiting apparent molal compressibility (φ0K), limiting apparent molal volume (φ0V), the associated constants (SK , SV) and the viscosity B coefficient of the Jones-Dole equation were calculated. These parameters were used to study the ion-solvent interaction present in each solution.
