What is the purpose of writing a net ionic equation?

To balance the chemical equation correctly

To show the dissociated ions involved in a chemical reaction

To represent spectator ions that do not participate in the reaction (correct)

To show all ionic compounds used as sources of reactants

In a net ionic equation, what does the presence of spectator ions indicate?

The products formed in the reaction

Ions that do not undergo any change during the reaction (correct)

Ions that are highly reactive

The reactants involved in the reaction

What does a complete ionic equation represent?

Only the reactants and products in their molecular form

Spectator ions only

All ions present in the solution as dissociated ions (correct)

The net charge of the ionic compounds
