文摘
- •
Solvation of solutes in water and in KH2PO4 aqueous solutions is an exothermic process.
- •
All saccharides except 2de-Glc give negative values of partial molar isentropic compressibility.
- •
Decrease in hydration number of solutes in the presence of KH2PO4 show its dehydration effect on the solutes.
- •
Studies indicate the dominance of hydrophilic–ionic interactions and kosmotropic behavior of solutes in KH2PO4 solutions.
