Abstract: Measurement of ultrasonic velocity, density and viscosity at different concentrations of citric acid in water, dimethylformamide, dimethylsulphoxide, and their mixtures have been carried out at 303 K using ultrasonic interferometer at frequency 2 MHz. The data obtained are used to evaluate various acoustic parameters in view of identification of the presence of ion-solvent interaction under prevailing conditions. Ultrasonic velocity has been found to increase with increase in the composition of DMSO and to decrease with DMF in water. The compressibility has been found to decrease with the increase in concentration for all compositions indicating the increase in ion-solvent interaction.
