ABSTRACT
In this work, density q, and speed of sound u, for citrate salts trisodium citrate (TSC) and tripotassium citrate (TPC) have been measured in (0.005, 0.01, 0.03 and 0.05) mol kg 1 aqueous solution of ionic liquid 1-butyl-3-methylimidazolium tetrafluoro borate ([C4mim][BF4]) at different temperatures T = (288.15, 293.15, 298.15, 303.15, 308.15) K at experimental pressure p = 0.1 MPa. Different parameters such as apparent molar volume (V/), partial molar volume (V/ 0 ), and standard partial molar volumes of transfer (DV/ 0 ) have been calculated by using the experimental density data. From experimental speed of sound data apparent molar isentropic compression (K/,s), partial molar isentropic compression (Ko /;s), and partial molar isentropic compression of transfer (DKo /;s) have been calculated. The pair and triplet interaction coefficients have been calculated from transfer parameters. Infrared spectral studies have also been carried out for the present mixtures. Work is mainly concerned with the study of the interactions present in the mixtures of trisodium citrate and tripotassium citrate in aqueous solutions of ionic liquid 1-butyl-3- methylimidazolium tetrafluoro borate [C4mim][BF4].
