General Chemistry Week 9 Part Two Predicting When Precipitates Will Form  Write all of ions present in the reaction  Compare all possible combinations according to solubility rules Q: Will a precipitate form when aqueous solutions of Pb(NO3)2 A: Pb(NO3)2 (aq) + 2KI(aq)  PbI2 (s) + 2KNO3 (aq) Q: Will a precipitate form when aqueous solutions of Ca(NO3)2 and KI mix A: No, no reaction will occur Net Ionic Equations Balanced Equation: Pb(NO3)2 (aq) + 2KI(aq) ▯ PbI2 (s) + 2KNO3 (aq) Ionic Equation: Pb+2 (aq) + 2NO3­ (aq) + 2K+ (aq) + 2I­ (aq) PbI2 (s) + 2K+(aq0 + 2NO3­ (aq) Net Ionic Equation: Pb+2(aq) + 2I­(aq) PbI2(s)  Spectator ions are not included in the net ionic equation: not involved i
