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

The density (ρ), viscosity ( ) 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 ( K), apparent molal volume ( V), limitingapparent molal compressibility ( K0 ), limiting apparent molal volume ( V0 ), theassociated 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.
