Ultrasonic Velocity and Density Studies of Solutions of Maleic Acid and Tartaric Acid in Water at T = (298.15 and 308.15) K

Ultrasonic-velocity and density measurements of aqueous solutions of maleic acid and tartaric acid have been made as a function of molality, at T = (298.15 and 308.15) K, and at atmospheric pressure. A molality range has been studied from (0.2603 to 2.6309) mol·kg−1 and (0.4451 to 2.6621) mol·kg−1 for maleic and tartaric acids, respectively. The experimental data have been correlated with molality using a polynomial equation. Furthermore, apparent molar volume, partial molar volume, apparent-specific molar volume, isentropic compressibility, apparent molar isentropic compressibility, limiting apparent molar isentropic compressibility, and isentropic apparent-specific compressibility values have been calculated from experimental values of densities and ultrasonic velocities. The calculated parameters have been interpreted in terms of solute–solvent interactions, solute–solute interactions, structure making/breaking behavior of acids, and their taste quality in water.
