H. N. Pawar | R. V. Dudhate | S. D. Deosarkar

Abstract: In order to disclose different interactions in aqueous solutions of caffeine in1,3,7-trimethylxanthine (trisodium citrate) solutions, the density, ultrasonic velocity and refractive index of these solutions have been measured at 30oC. Apparent molar volumes and compressibilities of studied solutions were calculated form densities and ultrasonic velocities respectively. Partial molar properties were determined form concentration dependence of apparent molar properties using standard equations. The transfer volumetric and acoustical properties have been computed and all the parameters were interpreted in terms of different interactions in aqueous solutions.

Keywords: Density, ultrasonic velocity, partial molar volume, partial molar compressibility
