Abstract

 Conductivity method is used for the study of the dissolution of Ca(OH)2 in water and in mixed solvent systems. The thermodynamic parameters for the dissolution of Ca(OH)2 such as ΔG°, ΔS°, ΔH° were calculated from solubility values at different temperatures in aqueous medium and in mixed solvent systems (Water+1-propanol, water+2-propanol,water+DMSO and water + THF). It was found that the solubility and solubility product of Ca(OH)2 significantly decreased linearly by increasing percentage composition of the mixed solvent systems. The Gibbs free energy ΔG°, enthalpy ΔH° and ΔS° were also changed. These results were in agreement with the dielectric constant value of the solvents used in the study.
