Abstract

The experimental and calculated solubilities of potassium fluoride in aqueous solutions were investigated at various temperatures. The experimental solubility of KF in aqueous solutions was determined up to m_max = 17.50 to 25.80 mol kg^−one respectively from 298.15 to 353.15 K. The calculated solubility requires the thermodynamic backdrop of the binary organization based on the water activity measurements. Accordingly, the water activity of KF aqueous solutions were measured from diluted to the saturated solutions, using the hygrometric method at different temperatures. The related thermodynamic backdrop of KF(aq) were evaluated by the development of ion interaction model. The new binary parameters (β⁽⁰⁾ _(G,F), β⁽¹⁾ _(K,F) , and C^φ _(KF) ) were determined at diverse temperatures and used to evaluate the solute activity and the osmotic coefficients ranging from 298.15 to 353.15 Thou. The solubility product of KF_(s) (given in ${50 northward Grand}_{southward p}^{°}$ ) and the standard molar Gibbs energies of dissolution ${Δ Yard}_{d i s s}^{°}$ were as well given at different temperatures.
