Although it is an ionic compound, it does not dissociate much into its ions in water, however a small amount does dissolve.When the small amount of BaF2 is dissolved in H2O (water) it will dissociate (dissolve) into Ba 2+ and F- ions. Which is more soluble in water BaF 2 or BeF 2 ?? Please answer quick. Such a solution is called saturated. However, compounds that we know to be highly soluble, like salt, are likely to form solutions at various ratios; in this case, we will be able to determine how much solute and solvent is needed to form each solution, and if it's possible to form one at all. Question = Is SbCl5 ( Antimony pentachloride ) polar or nonpolar ? Question: Is calcium oxidean ionic or covalent bond ? 1 Approved Answer. What is the molar solubility of BaF2 in water?
