| Abstract: | Apparent molar volumes and adiabatic
compressibilities of glycine ( 0.05-0.30 mol kg-1) in aqueous mannose, maltose and raffinose solutions ranging from pure
water to 6.0 mass % of saccharides have been determined at 288.15, 298.15 and
308.15 K from precise measurements of density and speed of sound. Partial molar
volumes and partial molar adiabatic compressibilities of glycine at infinite
dilution are evaluated. These values are used for calculating the number of
water molecules hydrated to glycine molecule. Transfer volumes and transfer
adiabatic compressibilities at infinite dilution from water to aqueous
saccharide solutions have also been calculated. Transfer parameters have been
interpreted in terms of solute-cosolute interactions on the basis of cosphere
overlap model. Pair and triplet interaction coefficients have also been
calculated from transfer parameters. |
