  1. Net Ionic Equations

  2. Show the physical state of each component in the reaction • If a compound is soluble, it is broken into appropriate aqueous ions

  3. Example 2: Fe(s) + AgNO3(aq)  ? • Molecular Equation: Fe(s) + 2AgNO3(aq)  2Ag(s) + Fe(NO3)2(aq) • Total Ionic Equation: Fe(s) + 2Ag+(aq) + 2NO3-(aq)  2Ag(s) + Fe2+(aq) + 2NO3-(aq) • Net Ionic Equation: Fe(s) + 2Ag+(aq)  2Ag(s) + Fe2+(aq) Spectator Ions: ion that exists as a reactant and a product in a chemical equation They simply "watch" the other ions react

  4. Pb(NO3)2 (aq) + 2 HCl (aq) ? • Molecular Equation: Pb(NO3)2 (aq) + 2 HCl (aq) PbCl2 (s) + 2 HNO3 (aq) • Total Ionic Equation: Pb2+(aq) + 2 NO3‾ (aq) + 2 H+(aq) + 2 Cl‾ (aq) PbCl2(s) + 2 H+(aq) + 2 NO3‾ (aq) • Net Ionic Equation: Pb2+(aq) + 2 Cl‾ (aq) PbCl2(s) A precipitate was formed
