“…Freidman et al have also made theoretical developments using the Gurney cosphere effect to account for the osmotic and activity coefficient properties in detail. , In solution, the solvation and the interactions of the ions or ion pair with the solvent determine the unique properties of these systems . The volumetric and acoustic properties of electrolytic and nonelectrolytic solutions have proved particularly informative in elucidating the various solute−solvent interactions that exist in these solutions. − Acoustic, volumetric and osmotic data for IL-containing systems are of great relevance in assessing intermolecular interactions between the IL and solvent and also for the development of thermodynamic models specific to IL-containing systems.…”

Experimental measurements of density at different temperatures ranging from 293.15 to 313.15 K, the speed of sound and osmotic coefficients at 298.15 K for aqueous solution of 1-ethyl-3-methylimidazolium bromide ([Emim][Br]), and osmotic coefficients at 298.15 K for aqueous solutions of 1-butyl-3-methylimidazolium chloride ([Bmim][Cl]) in the dilute concentration region are taken. The data are used to obtain compressibilities, expansivity, apparent and limiting molar properties, internal pressure, activity, and activity coefficients for [Emim][Br] in aqueous solutions. Experimental activity coefficient data are compared with that obtained from Debye-Hückel and Pitzer models. The activity data are further used to obtain the hydration number and the osmotic second virial coefficients of ionic liquids. Partial molar entropies of [Bmim][Cl] are also obtained using the free-energy and enthalpy data. The distance of the closest approach of ions is estimated using the activity data for ILs in aqueous solutions and is compared with that of X-ray data analysis in the solid phase. The measured data show that the concentration dependence for aqueous solutions of [Emim][Br] can be accounted for in terms of the hydrophobic hydration of ions and that this IL exhibits Coulombic interactions as well as hydrophobic hydration for both the cations and anions. The small hydration numbers for the studied ILs indicate that the low charge density of cations and their hydrophobic nature is responsible for the formation of the water-structure-enforced ion pairs.

This review gives a short introduction into the principles of sound velocity measurements. The fundamentals of acoustical methods using continuous waves, pulse modulated signals and sharp pulses are summarized. Methods employing optical wave interactions with continuous ultrasonic waves are also described briefly. Recent advances in the different methods are presented, and the technical status of the currently preferred techniques is discussed in view of their merits and limitations, too. Particular emphasis is given to the sensitivity and accuracy of the methods. Selected examples of measurement applications indicate the extended usability spectrum in basic research as well as in materials' characterization, manufacturing processes and control routines.
