Abstract
Volumetric and transport properties of ternary aqueous solutions of tripotassium 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) mol·kg–1] at T = (293.15 to 313.15) K. The apparent molar volume and apparent molar isentropic compressibility have been calculated from the measured density and speed of sound data for ternary aqueous solutions of tripotassium citrate. The apparent molar volume and apparent molar isentropic compressibility of ternary aqueous solutions of tripotassium citrate + (KBr or KNO3) have been correlated with the Redlich–Mayer equation. Viscosity values of ternary aqueous solutions of tripotassium citrate + (KBr or KNO3) have been fitted with the Jones–Dole equation. The results obtained have been interpreted in elucidating the effect of KBr or KNO3 and temperature on the interaction of tripotassium citrate with water. Furthermore, density and viscosity values of ternary aqueous solutions of tripot...
