Acoustical Studies of Some Bio-Molecule Aqueous Solution at Different Temperatures Using Ultrasonic Technique

Sangita Shinde

Abstract: Acoustic investigations make innovations in the study of molecular interactions of solute-solute, solute-solvent, solvent-solvent in liquids. The ultrasonic parameters are directly related to a number of thermodynamic parameters. The interactions of urea and molecular dynamics, solute in solvent have been investigated by ultrasonic technique. The ultrasonic velocities and densities have been measured for aqueous solution of Gelatin as a function of concentration, at four different temperatures 298.15K, 303.15K, 308.15K and 313.15K and frequency 2MHz. The experimental data have been used to compute the thermodynamic properties namely adiabatic compressibility (), intermolecular free length () and specific acoustic impedance () for the binary mixtures with a view to investigate the solute-solute and solute-solvent interactions. These thermodynamic parameters have been further used to elicit the ion-ion and solute-solvent in the binary mixtures.

Keywords: Ultrasonic velocity, density, adiabatic compressibility, acoustic impedance, intermolecular free length, gelatin
