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. Referencing the periodic table below will help you work through the elemental names and groups. While we can calculate the solubility by measuring each substance and following an equation, the solubility rules allow us to determine the solubility of a substance before you attempt to create it. Short Answer A saturated solution of BaF2 at 25C is prepared by equilibrating solid BaF2 with water. The refractive index is about 1.46 from 700nm to 5m.[11]. Powdered NaF is then dissolved in the solution until the solubi lity of BaF2 is 1.0% of that in H2O alone. Hence, in pure water the molar solubility is 7.5110-3mol/L.
