Solubility in the systems of CuCl-LiCl-H2O and CuCl-CsCl-H2O at 25°C was studied by the method of isothermal removal of oversaturation. The solubility of the chlorides decreases as we go down the group as the hydration enthalpy of the ions decreases at a greater rate than the lattice enthalpy of these chlorides. ‘ … Authors: Horne, J W; Christianson, L F Publication Date: Sat Jun 01 00:00:00 EDT 1940 Research Org. Mg, Ca , Ba , Sr are ionic ,have lower melting point than the fluorides and are readily soluble in water. Amongst fluorides of alkali metals, the lowest solubility of LiF in water is due to (a) ionic nature of lithium fluoride. This volume surveys the data available in the literature for solid-fluid solubility equilibria plus selected solid-liquid-vapour equilibria, for binary systems containing alkali and ammonium chlorides in water or heavy water. The solubilities of the metal halides LiF, LiCl, LiBr, LiI, NaF, NaCl, NaBr, NaI, KF, KCl, KBr, KI, RbCl, CsCl, CsI, were measured at temperatures ranging from 298.15 to 378.15 K in the ionic liquid 1-butyl-3-methylimidazolium trifluoromethanesulfonate ([C 4 C 1 im][OTf]). Alkali metal and ammonium chlorides in water and heavy water (binary systems) by , July 1, 1991, Pergamon edition, in English The solubility decreases somewhat with increasing atomic number. An association model with a cubic equation of state was adopted to calculate the solubilities of alkali metal chlorides in water vapor under high temperatures and pressures. Yes ,this order is correct. v) Solubility in liquid ammonia Alkali metals dissolves and form solution in liquid ammonia. All alkali metals hydroxides are soluble in water. Therefore, the solubility data of these alkali metal salts in water vapor at high temperatures and pressures are very important as a fundamental knowledge to design the supercritical water decomposition processes.
