Formation constant of the double salt CsCl·2NaCl·2H₂O(cr)
Formation constant of the double salt CsCl·2NaCl·2H₂O(cr)
In the ternary system CsCl – NaCl – H₂O, at a temperature of 298.15 K, a double salt with the stoichiometric formula CsCl∙2NaCl∙2H₂O(cr) is known to be formed. This double salt and the anhydrous CsCl(cr) are the end-members of a solid solution. For the pure double salt, the solubility constant was determined. The obtained value were applied to calculate the solubility diagram also of the quaternary system CsCl – NaCl – KCl – H₂O and the quaternary-reciprocal system Cs⁺, Na⁺ || Cl⁻, SO₄²⁻ – H₂O. The solubility constant together with a solid solution between CsCl∙2NaCl∙2H₂O(cr) and CsCl(cr) were implemented in THEREDA, which extends the applicability of the existing cesium dataset.
