Are these statements contradictory because of the toxicity of beryllium compounds, which is why they have been studied less and are not spoken about frequently? If we know that a substance is insoluble, it is likely that it would have excess solute, thus forming a precipitate. I was going through JD Lee and I found certain contradictory statements. It is less resistant to water than calcium fluoride, but it is the most resistant of all the optical fluorides to high-energy radiation, though its far ultraviolet transmittance is lower than that of the other fluorides. chemistry.stackexchange.com/questions/127687/, We've added a "Necessary cookies only" option to the cookie consent popup.

At the same time, the BaF2 is a very different substance than Ba 2+ and F-.Knowing the solubility rules can help you determine whether BaF2 will dissolve in water and dissociate into ions (see https://youtu.be/zffVKN6tm7k). With most compounds, on descending the group, the hydration energy decreases more rapidly than the lattice energy: hence the compounds become less soluble as the metal gets larger. Sodium chloride contains Na, which is almost always soluble according to rule 1, and Cl, which is usually soluble according to rule 3. The solubility is equal to the concentration of the Ba ions in solution.solubility = [Ba+] = 7.94 x 10-3 M[F-] = 2 [Ba+]Ksp = [Ba+][F-]2Ksp = ([Ba+])(2 [Ba+])2Ksp = 4[Ba+]3Ksp = 4(7.94 x 10-3 M)3Ksp = 4(5 x 10-7)Ksp = 2 x 10-6. BeF2 is soluble in water due to evolution of large hydration energy, when it is dissolved in water, which is sufficient enough to overcome the lattice energy of the Berylium Flouride, as for a compound to be soluble in water, the lattice energy of the compound must be less than the hydration energy evolved upon dissolution in water. Solubility in / Miscibility with Water at 25 C (77 F): 1.2 g/l Soluble Partition coefficient (n-octanol/water): No data available. Thus, s=21[F ]. There are few exceptions to this rule.

Short Answer A saturated solution of BaF2 at 25C is prepared by equilibrating solid BaF2 with water. It is very important that the rules on this list are followed in order, because if a rule seems to contradict another rule, the rule that comes first is the one that you follow. Solubility depends entirely on the physical and chemical properties of the solute and solvent, and isnt affected by the rate of solution. Since on descending the group lattice energy decreases more rapidly than the hydration energy. In general, the solubility of a substance depends on not only the energetic factors we have discussed but also the temperature and, for gases, the pressure. Referencing the periodic table below will help you work through the elemental names and groups. Wikipedia says $\ce{BeF2}$ is highly soluble, whereas $\ce{CaF2}$ is insoluble. (aq) + CO3 2- (aq).
