ABSTRACT

Densities, ?, and speeds of sound, u, for trisodium citrate and tripotassium citrate in (0.01 and 0.03) mol*kg 1 in aqueous solutions of 1-hexyl-3-methylimidazolium chloride ([C6mim][Cl]) over a range of temperatures T = (288.15, 293.15, 298.15, 303.15, 308.15) K have been measured at atmospheric pressure. The experimental densities are used to calculate the apparent molar volume, limiting apparent molar volumes, and transfer volumes. Experimental values of the speed of sound were used to estimate apparent molar isentropic compression, limiting apparent molar isentropic compression, and transfer parameter. The structure making or breaking ability of 1-hexyl-3-methylimidazolium chloride has been discussed in terms of the sign of (?2V?0/?T2). The UV absorption studies have also been made in this study. The results have been discussed in terms of competing patterns of interactions prevailing in the solute and solvent, that is, citrate salt + [C6mim][Cl] + water mixtures.
