Modeling and Experimental Measurement of NaCl and KCl Solubility: A Laser Monitoring-Based Method

Abstract

This study presented the experimental data for NaCl and KCl solubility in the 1-propanol, 2-propanol, 1-butanol, acetonitrile, and propylene glycol. The solubility values were measured by a laser-based technique at 293.15–313.15 K and the generate data were correlated to some mathematical models and their accuracy was studied by the mean relative deviations for the back-calculated data. Furthermore, the apparent thermodynamic parameters of NaCl and KCl dissolution were also studied according to the van’t Hoff and Gibbs equations.
