Types of Equations for Reactions in Aqueous
Solutions

• 3 types
• Molecular-shows overall reaction but not all
  forms of reactants and products in solution
• Complete ionic-represents all reactants and
  products that are strong electrolytes as ions.
• Net ionic-includes only the components that
  undergo a change, not spectator ions.
