  1. Reactions in Aqueous Solutions Molecular Equations Complete Ionic Equations Net-Ionic Equations

  2. Molecular Equation • A molecular equation gives the overall reaction. • Although it gives the Stoichiometry, it gives no information if any compound is ionic in solution. • Solid states are represented by  or (s). • 2KCl (aq) + Pb(NO3)2 (aq)  PbCl2 + 2KNO3 (aq)

  3. Complete Ionic Equation • It includes all the ions in solution. • The states of all compounds are aqueous, unless otherwise indicated. • Solid states are represented by  or (s). • 2K+ + 2Cl- + Pb+2 + 2NO3-  PbCl2 + 2K+ + 2NO3-

  4. Net-Ionic Equation • It only gives information on species that undergo a chemical change. • The spectator ionsare omitted from the complete ionic equation. • Solid states are represented by  or (s). • Pb+2 + 2Cl- PbCl2 
