Answer:
The molecular equation shows each of the substances in the reaction as compounds with physical states written next to the chemical formulas. The
complete ionic equation shows each of the aqueous compounds as separate ions. Insoluble substances are not separated and these have the symbol (s) written
next to them. Water is also not separated and it has a (l) written next to it. Notice that there are ions that are present on both sides of the reaction arrow –>
that is, they do not react. These ions are known as spectator ions and they are eliminated from complete ionic equation by crossing them out. The remaining
equation is known as the net ionic equation. For example: The reaction of potassium chloride and lead II nitrate
Molecular Equation: 2KCl (aq) + Pb(NO3)2 (aq) -> 2KNO3 (aq) + PbCl2 (s)
Complete Ionic Equation: 2K+ (aq) + 2Cl-
(aq) + Pb2+ (aq) + 2NO3–
(aq) -> 2K+
(aq) + 2NO3
–
(aq) + PbCl2 (s)
Net Ionic Equation: 2Cl-
(aq) + Pb2+ (aq) -> PbCl2 (s)
