  1. NO31– NO31– NO31– NO31– Pb2+ Pb2+ Na1+ Na1+ I1– I1– Ions in Aqueous Solutions Dissociation: Molecular Equation Pb(NO3)2(s) + H2O(aq) Pb(NO3)2(aq) Pb2+(aq) + 2 NO31–(aq) add water Ions in solution NaI(s) + H2O(aq) NaI(aq) Molecular Equation Na1+(aq) + I1–(aq) add water Ions in solution Mix them and get…

  2. Pb(NO3)2(aq) + 2 NaI(aq) + 2 Na1+(aq) PbI2(s) + 2 NO31–(aq) NO31– NO31– NO31– NO31– Pb2+ Pb2+ Na1+ Na1+ Na1+ Na1+ I1– I1– I1– I1– + 2 Na1+(aq) + 2 I1–(aq) Pb2+(aq) + 2 NO31–(aq) + 2 Na1+(aq) PbI2(s) + 2 NO31–(aq) Pb2+(aq) + 2 I1–(aq) PbI2(s) Mix them together and get… solid in solution Balance to get overall ionic equation… Cancel spectator ions to get net ionic equation…

  3. Zn(NO3)2(aq) + Ba(OH)2(aq) + Ba2+(aq) Zn(OH)2(s) + 2 NO31–(aq) OH1– NO31– Ba2+ Zn2+ NO31– OH1– + Ba2+(aq) + 2OH1–(aq) Zn2+(aq) + 2 NO31–(aq) + Ba2+(aq) Zn(OH)2(s) + 2 NO31–(aq) Zn2+(aq) + 2 OH1–(aq) Zn(OH)2(s) Mix together Zn(NO3)2(aq) and Ba(OH)2(aq): Mix them and get… Zn(NO3)2(aq) Ba(OH)2(aq) Zn2+(aq) + 2 NO31–(aq) Ba2+(aq) + 2 OH1–(aq) Balance to get overall ionic equation… Cancel spectator ions to get net ionic equation…

  4. Three Double Displacement Acid-Base (Neutralization): an acid and base form salts and water. ie. HCl(aq) + NaOH(aq) NaCl(aq) + H2O Gas Evolution: reaction where a gas is formed. ie. H2SO4(aq) + Li2S(aq) H2S(g) + Li2SO4(aq) Precipitation: a precipitate is formed from two soluble substances. ie. 2KI(aq) + Pb(NO3)2(aq) PbI2(s) + 2KNO3(aq)

  5. Redox Reactions: How They Work • 2Mg (s) + O2 (g) → 2MgO (s) Each Mg loses 2 e-; Each O gains 2 e- 2. Ca (s) + Cl2 (g) → CaCl2 (s) Ca loses 2 e-; Each Cl gains 1 e- 3. Zn (s) + Fe2+ (aq) → Zn2+ (aq) + Fe (s) Zn loses 2 e-; Fe gains 2 e-
