ABSTRACT

Solubilities, densities, and refractive indices have been measured for the four ternary systems, ethylene glycol + NaCl + H2O, ethylene glycol + KCl + H2O, ethylene glycol + RbCl + H2O, and ethylene glycol + CsCl + H2O, at T = 298.15 K, with mass fractions of ethylene glycol ranging from 0 to 1.0. Polynomial equations of fit are proposed for the solubility of the saturated solutions as a function of the mass fraction of ethylene glycol. The equations proposed also account for the density and refractive index for the saturated solutions. On the other hand, the density and refractive index of unsaturated solutions were also determined for the same ternary systems with varied undersaturated salt concentrations. Values for both the properties were also correlated with the salt concentrations and proportions of ethylene glycol in the undersaturated solutions. In all the cases, the presence of ethylene glycol significantly reduces the solubility of the salts in the aqueous solution.
