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 Trial Ksp is also sometimes referred to as Qsp . SOLUBILITY PROBLEMS. Calculate the solubility product, K … Solubility is the amount of reagent that will be consumed to saturate the solution or reach the equilibrium of the dissociation reaction. If Qsp = Ksp the system is in equilibrium . Calculate the solubility product. 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. Solubility Product Practice Problems. 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-. The solubility would then equal the concentration of either the Ag or Cl ions.solubility = [Ag+] = [Cl-]1.26 x 10-5 M = [Ag+] = [Cl-]Ksp = [Ag+][Cl-]Ksp = (1.26 x 10-5)(1.26 x 10-5)Ksp = 1.6 x 10-10, The dissociation reaction of BaF2 in water isBaF2 (s) ↔ Ba+ (aq) + 2 F- (aq)This reaction shows that for every mole of BaF2 that dissolves, 1 mole of Ba+ and 2 moles of F- are formed. Calculate the solubility product. Solutions . The solubility product of barium fluoride (BaF 2) is 2 x 10-6 at 25 °C. Problem . Here are some practice problems for writing K sp expressions.
