Ultrasonic Analysis of Aqueous Ascorbic Acid at Temperature 303K

V. G. Dudhe | V. A. Tabhane | O. P. Chimankar

Abstract: The ultrasonic velocity (U), density () and viscosity () of different concentration of aqueous ascorbic acid (vitamin C) have been studied at temperature 303K. The measurement of ultrasonic velocity were carried out by using the ultrasonic pulse eco overlap (PEO) technique at frequency 5 MHz. Measurement of density have been carried out by using hydrostatic plunger method and viscosity by Oswalds viscometer. The temperature 303K have been kept constant using thermostat by circulating water. Experimental data have been used to estimate the thermo-acoustical parameters such as adiabatic compressibility (), acoustic impedance (z), free length (Lf), free volume (Vf) internal pressure (Pi), wadas constant (m) and Raos constant (R). These parameters have been used to give the interpretations of solute solvent interaction of water and ascorbic acid molecules. Furthermore these studies shows that the nature of molecular interaction and complex formation in solution of ascorbic acid (vitamin C) and it provide important information regarding molecular properties of solute and solvent interaction.
