The answer that Barium fluoride is Slightly Soluble in water. 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. Thalliumthiocyanate (2TlSCN) is only slightly in water. However, the process of solubility is unique, and the rate at which it dissolves is not factored into the equation. http://periodic-table-of-elements.org/SOLUBILITY. This is a useful factor in qualitative analysis. Hydroxide salts of Group I elements are soluble. All rights reserved. The solubility of a substance is an entirely different property from the rate of solution, which is how fast it dissolves. BaF2s Ba2+aq+2F-aq- s 2s. thus the randomness of the molecules increases= positive S Important exceptions to this rule include CaSO4, BaSO4, PbSO4, Ag2SO4 and SrSO4 . Powdered NaF is then dissolved in the solution until the solubi lity of BaF2 is 1.0% of that in H2O alone.
