Richard D’ Souza, G.Meenakshi

Abstract: The physical properties that has been investigated are, density (?),viscosity (?), and ultrasonic velocity (U) of L-valine, L- leucine and L-glutamine in aqueous n-propanol solution (0%-30%) in steps of 10% at 308.15K have been measured. The derived acoustical parameters namely adiabatic compressibility (ß), apparent molal compressibility (?K), apparent molal volume (?V), limiting apparent molal compressibility(?°K), limiting apparent molal volume(?°V) and their constants (sk , sv), transfer adiabatic compressibility (??°K), transfer volume(??°V) , and viscosity B-coefficient are calculated using the experimental data. The change that has been observed in the parameter with respect to molality of the solute has been interpreted in terms of ion-ion and ion- solvent interactions.

Keywords: Molecular interaction, solute-solvent interaction, ion-ion interaction, ion-solvent interaction
