ABSTRACT

Volumetric and transport properties of ternary aqueous solutions of tri-potassium citrate in (KBr or KNO3) + water have been determined in the different molality ranges of KBr and KNO3 (0.2, 0.3, 0.4, 0.5, 0.6 and 0.7) at T = (293.15 to 313.15) K. Apparent molar volume and apparent molar isentropic compressibility have been calculated from the measured density and speed of sound for ternary aqueous solutions of tri-potassium citrate. Apparent molar volume and apparent molar isentropic compressibility of ternary aqueous solutions of tri-potassium citrate + (KBr or KNO3) have been correlated with Redlich-Mayer equation. Viscosity values of ternary aqueous solutions of tri-potassium citrate + (KBr or KNO3) have been fitted with Jones-Dole equation. The obtained results have been interpreted in elucidating the effect of KBr or KNO3 and tempreature on the interaction of tri-potassium citrate with water.Furthermore density and viscosity values of ternary aqueous solutions of tri-potassium citrate + (KBr or KNO3) have successfully been predicted using the methods proposed by Laliberte' et al. and Zafarani-Moattar et al. for mixtures of inorganic salts.
