The measurement of ultrasonic velocity, adiabatic compressibility, free length and acoustic impendence are novel tools
for investigation of properties of compound, nature of intermolecular interaction between components in homogeneous solution.
The density, viscosity and ultrasonic velocity of different concentration of aqueous solution L-arginine have been studied at
different temperature. From experimental data different thermo acoustic parameters like adiabatic compressibility, free length
and acoustic impendence have been evaluated. The nature of solute, solute-solvent interactions in this system was also studied.
