Ultrasonic Study of Molecular Interactions in Organic Liquids at Various Temperatures and Concentrations

Abstract

The ultrasonic velocity was measured for water and glacial acetic acid in their pure state and in their binary mixtures. The ultrasonic velocity was measured also for the solution of salicylic acid in glacial acetic acid. Relative density and relative viscosity were also measured at various temperatures and concentrations. The parameters like adiabatic compressibility, acoustic impedance, relaxation time and attenuation were determined. This study is helpful for the understanding of the macroscopic structure solute–solute and solute–solvent interactions.
