Abstract: Apparent molar volumes (ϕv) of three monosaccharides [D(-)-arabinose, D(-)-ribose, D(+)-glucose] and one disaccharide [sucrose] in water and in 0.5, 1.0, 2.0 and 4.0 mol kg-1 aqueous cupric chloride and zinc chloride solutions at 298.15K have been determined from density measurements using a vibrating-tube digital densitymeter. Partial molar volumes (V02) at infinite dilution obtained from ϕv values have been used to calculate partial molar volumes of transfer V02,tr for various saccharides from water to aqueous cupric chloride/zinc chloride solutions. V02,tr values are positive for all the saccharides studied and increase with increase in concentration of cosolutes. The V02,tr values have been rationalized in terms of solute-cosolute interactions using a cosphere overlap hydration model. Pair and triplet interaction coefficients have been calculated using McMillan-Mayer approach and their sign and magnitude have also been discussed.
