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 offatcat:qg6tf2fws5euznwtcqmgpiejte
