Experimental investigation of the stability of a chloroborate complex and thermodynamic description of aqueous species in the B-Na-Cl-O-H system up to 350°C

Geochemistry International volume 44, pages867–878(2006)Cite this article

Abstract

The solubility of chlorargyrite, AgClcr, was experimentally studied in NaCl solutions (0.1, 0.2, and 0.5 m) as a function of the concentration of boric acid (up to 5 m) at 70–300°C and saturated water vapor pressure. The experimental data indicated the existence of the chloroborate species B(OH)3Cl−. The published data on the thermodynamic properties of aqueous complexes in the B-Na-Cl-O-H system were analyzed. The obtained HKF parameters of aqueous species can be used to calculate equilibria in the system up to 350°C.
