The volumetric and ultrasonic properties of sucrose in aqueous solutions of citrate salts trisodium citrate (TSC) and tripotassium citrate (TPC) were studied at temperatures T = (288.15-318.15) K and at atmospheric pressure. Apparent molar volumes V-phi and apparent molar isentropic compressibilities K-phi,K-s were calculated from measured density rho and speed of sound u data. Partial molar volumes V-phi degrees and partial molar isentropic compressibilities K-phi,K-s degrees at infinite dilution, transfer parameters Delta V-phi degrees and Delta K-phi,K-s degrees of sucrose from water to aqueous solutions of TSC and TPC, expansion coefficients (partial derivative V-phi degrees/partial derivative T)(p), (partial derivative V-2(phi)degrees/partial derivative T-2)(p), and interaction coefficients (V-AB, K-AB)(V-ABB, K-ABB) were also evaluated. These parameters are discussed in terms of solute-cosolute interactions to understand the solvation behavior of sucrose in theses salts. Positive and increasing values of Delta V-phi degrees, with increasing citrate salt concentrations were obtained. This indicated the dehydration of the sucrose in the presence of the citrate salts due to the predominance of solute-cosolute interactions. Hydration number N-w was also calculated for the mixtures in this study.
