Calculation of the standard partial molal thermodynamic properties of KCl 0 and activity coefficients of aqueous KCl at temperatures and pressures to 1000°C and 5 kbar

Abstract

Regression of experimental activity coefficient and dissociation constant data reported in the literature with the Hückel (1925) and Setchénow (1892) equations (Helgeson et al., 1981) and the revised HKF equations of state (Tanger and Helgeson, 1988; Shock et al., 1989, 1992) generated parameters and thermodynamic properties of dissociated KCI and KCl 0 at 25°C and 1 bar that can be used to calculate the standard partial molal thermodynamic properties of KCl 0 and the activity coefficients of KCl at temperatures and pressures to 1000°C and 5 kbar.
