Acoustical Behaviour of Binary Solutions of Tartaric Acid

The nature of molecular interaction present in liquids and in various organic liquid mixtures can be studied by ultrasonic measurements. Ultrasonic velocities of solutions of Tartaric acid in water, methanol, ethanol, and propanol were measured at 15°C, 25°C, 35°C, 45°C and 55°C using an ultrasonic interferometer of frequency 2MHz. The ultrasonic velocity, density and viscosity of the solutions are used to calculate adiabatic compressibility, Rao's constant, Wada's constant and apparent molal compressibility. The obtained results indicate the presence of molecular interactions in the binary solutions studied.
