molar volumes (Vϕ) and
apparent molar isentropic compressions (Kϕ,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
(Vϕ0), partial molar isentropic compression (Kϕ,S0) at infinite dilution and their corresponding partial molar
volumes of transfer (ΔVϕ0), and partial molar isentropic
compression of transfer (ΔKϕ,S0). The expansibility parameter
(∂Vϕ0/∂T)P and its derivative (∂2Vϕ0/∂T2)P along with pair
(VAB, KAB)
and triplet (VABB, KABB) 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.
