CALCULATION OF THE STANDARD PARTIAL MOLAL THERMODYNAMIC PROPERTIES OF KCL0 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 Huckel (1925) and Setchenow (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 KCl and KCl0 at 25°C and 1 bar that can be used to calculate the standard partial molal thermodynamic properties of KCl0 and the activity coefficients of KCl at temperatures and pressures to 1000°C and 5 kbar.
