Abstract
–solvent interactions in aqueous solutions. The measured density and viscosity were used to derive the apparent molar volumes (φV), partial molar volumes () and viscosity B-coefficients at 298.15, 303.15, 308.15 and 318.15 K under ambient pressure. The interactions are further discussed in terms of ion–dipolar, hydrophobic–hydrophobic, hydrophilic–hydrophobic group interactions. The activation parameters of viscous flow are also discussed in terms of the transition state theory. The overall results indicated that ion–hydrophilic and hydrophilic–hydrophilic group interactions are predominant in the ternary solutions.
