of Ca(NO3)2 and Na2CO3 Complete Ionic Equation Spectator Ions
• Ions that are important for
delivering other ions into solution
but that are not actively involved in
the reaction are called spectator
• Spectator ions can be recognized
because they are separate and
surrounded by water molecules
both before and after the reaction. Net Ionic Equations
• An equation written without
spectator ions is called a net
