A molecular equation is an equation showing the complete neutral formula for each compound in a reaction. A complete ionic equation is an equation which lists individually all of the ions present as either reactants or products in a chemical reaction. A net ionic equation is an equation that shows only the species that actually change during a chemical reaction.
Work Step by Step
Within a molecule or a chemical reaction, there may be rearrangements of charges even when the net charge is zero and it's overall neutral. Molecular equations represent this neutral state, whereas ionic equations show charges involves even when the net is neutral.
