The system KCl - PbCl₂ - H₂O has been investigated by several workers. The compounds formed are KCl. PbCl₂.1/3H₂O, which is in equilibrium with solutions concentrated with respect to the KCl and KCl.2PbCl₂ in equilibrium with more dilute solutions. Their existence has been reported by Wells, Bronsted, who studies the system at 20°C, Demassieux, at 14°, 50° and 100°, and Burrage at 25°. On the other hand Herty obtained a salt to which he gave the formula KCl. PbCl₂, although his results were about 1% lower than required for this formula, and Kendall and Sloan claim that the definitely anhydrous salt KCl. PbCl₂ is formed at 25°C.
