Solubility of potassium fluoride in aqueous solution at different temperatures 298.15K–353.15K
No full textIn this investigation, the binary aqueous solutions of Potassium Fluoride have been studied using the hygrometric method at different temperatures 298.15K–353.15K. The water activities are measured at molalities from 0.10 mol kg−1 to saturation. The obtained data allow the deduction of osmotic coefficients. From these measurements, the ionic parameters are determined and used to predict the solute activity coefficients. Thermodynamic characteristics, solubility products K°sp and the standard molar Gibbs energy of dissolution ΔG°diss are given. The predicted solubility isotherms are compared with the literature data
