Abstract

Graphical abstract: Highlights: LiCl solutions in an ionic liquid and in water were investigated thermodynamically. Densities and speeds of sound were measured for these systems. Apparent molar volumes and isentropic compressions were calculated. Apparent molar isobaric expansions at infinite dilution were derived. Results were interpreted in terms of LiCl-ionic liquid and LiCl-water interactions. Abstract: Densities and speeds of sound for LiCl in 1-butyl-3-methylimidazolium tetrafluoroborate (bmimBF4 ) and in water were accurately measured as a function of concentration at five temperatures from 288.15 K to 308.15 K. Apparent molar volumes and isentropic compressions were calculated from the measured density and speed of sound data. Infinite dilution values of these derived thermodynamic properties were obtained by a suitable extrapolation procedure. The temperature dependence of apparent molar volumes at infinite dilution was also examined. The results were discussed in terms of interactions between LiCl and bmimBF4 in comparison with those between LiCl and water.
