Is BaF2 (Barium fluoride) soluble or insoluble in water? The answer that Barium fluoride is Slightly Soluble in water. Some will dissolve but only a small amount. • These are some of the basic rules for solubility ( • Solubility Rules: Explanation Prac... ): • Salts of: • Group I elements (Li+, Na+, K+, Cs+, Rb+) are • NH4+ (Ammonium ion) are soluble. • the nitrate ion (NO3-) are generally soluble. • of Cl-, Br-, and I- are soluble. Exceptions Ag+, Pb2+, and (Hg2)2+ • most sulfates are soluble. Exceptions: Ba2+, Ca2+, Pb2+, Ag+, Sr2+ • most hydroxide salts are only slightly soluble. Exceptions: NH4+, Li+, Na+, K+ • most carbonates (CO32-) are insoluble. Exceptions: Group 1 and NH4+ • Note: Rules at the top supersede any lower rules. • --- • We can also look a Solubility Table ( • How to Use the Solubility Table / Chart ). On the solubility table we can see that BaF2 (Barium fluoride ) is insoluble in water. • Solubility Chart used in video: https://en.wikipedia.org/wiki/Solubil... • Because it is insoluble in water, we would expect that it would NOT dissociate into its ions. • Solubility Resources: • Solubility Rules and the Solubility Table: • Solubility Rules: Explanation Prac... • Net Ionic Equations: • How to Write and Balance Net Ionic Eq... • Finding the Charge on Ions: • Figuring out the Charge on Ions • We could also just get some BaF2 and see if it dissolves in water, that would also tell us if it is soluble or insoluble. • Based on the solubility rules and solubility chart we would expect Barium fluoride to be insoluble in water. Note that a very small amount of BaF2 would dissolve but very little.
