Apparent molar volumes (V-phi) and apparent molar isentropic compressions (K-phi,K-s) for some monosaccharides {D(+)-glucose, D(-)-fructose, D(+)-xylose and D(-)-ribose} in (0.0, 0.2, 0.4, 0.6) mol.kg(-1) aqueous solutions of tripotassium citrate (TPC) have been determined from density and speeds of sound measurements along four isotherms at temperatures between (288.15 and 318.15) K at experimental pressure p = 0.1 MPa using an automated vibrating tube densimeter (Anton Paar DSA 5000 M). The experimental values are used to determine partial molar volume (V-phi(0)), partial molar isentropic compression (K-phi,s(0)) at infinite dilution and their corresponding partial molar volumes of transfer (Delta V-phi(0)), and partial molar isentropic compression of transfer (Delta K-phi,s(0)). The expansibility parameter (partial derivative V-phi(0)/partial derivative T)(p) and its derivative (partial derivative V-2(phi)0/partial derivative T-2)(p) along with pair (V-AB, K-AB) and triplet (V-ABB, K-ABB) interaction coefficient for density and speed of sound data have been determined. The interpretation of the data has been made in terms of solute solvent interactions.
