The solubility of silver chloride, AgCl, is 1.26 x 10-5 M at 25 °C.The solubility of barium fluoride, BaF2, is 3.15 x 10-3 M at 25 °C.Calculate the solubility product, Ksp, of both compounds. Problem . Calculate the solubility of both compounds. To find these concentrations, remember this formula for solubility product: The dissociation reaction of BaF2 in water is: The solubility is equal to the concentration of the Ba ions in solution. Write the chemical equation showing how the substance dissociates and write the K sp expression: PART 1: 1) AlPO 4 2) BaSO 4 3) CdS 4) Cu 3 (PO 4) 2 5) CuSCN 6) Hg 2 Br 2 7) AgCN 8) Zn 3 (AsO 4) 2 9) Mn(IO 3) 2 10) PbBr 2 11) SrCO 3 12) Bi 2 S 3 ANSWERS For every mole of Ba+ ions formed, 2 moles of F- ions are produced, therefore: Todd Helmenstine is a science writer and illustrator who has taught physics and math at the college level. This page is a brief introduction to solubility product calculations. These are covered in more detail in my chemistry calculations book. Conditions for precipitation are Qsp > Ksp. We then substituted the relationship between the concentrations of these ions and the solubility … The solubility product of AgCl is 1.6 x 10-10.The solubility product of BaF2 is 2 x 10-6. The solubility would then equal the concentration of either the Ag or Cl ions. A saturated solution of calcium fluoride CaF 2 in water on analysis was found to contain at 298 K 1.7 x 10-3 g per 100 cm 3. Calculate the solubility product. Here are some practice problems for writing K sp expressions. Let's focus on one step in Practice Problem 4.We started with the solubility product expression for Ag 2 S.. K sp = [Ag +] 2 [S 2-]. The dissociation reaction of AgCl in water isAgCl (s) ↔ Ag+ (aq) + Cl- (aq)For this reaction, each mole of AgCl that dissolves produces 1 mole of both Ag+ and Cl-. He holds bachelor's degrees in both physics and mathematics. The solubility product of barium fluoride (BaF 2) is 2 x 10-6 at 25 °C. This example problem demonstrates how to determine the solubility product of an ionic solid in water from a substance's solubility. Calculate the solubility product.
