Abstract
Influence of the various factors on solubility in water of fluorides of alkaline and alkaline – earth metals of composition MF (M – Li ÷ Cs) and M’F2(M – Be ÷ Ba) is considered. The defining role of the factor of basicity, and also the magnitudes connected with energy of a crystal lattice (boiling temperature and enthalpy of evaporation) on solubility of salts is established. It is shown that the minimum solubility (LiF, CaF2) is reached at of value of the factor of basicity slightly less than 1. Possibility of formation of complex fluorides of the metals and change of their solubility compared to the initial components is predicted.
