The net Ionic equation provides the knowledge of ions which exists in an aqueous medium. Salts get dissolved in polar solvents like water and present as cations and anions in the dissolved state. The net ionic equation indicates the chemical species which undergo a chemical change. The ions which appear on both sides of the equation remain constant and therefore considered to be spectator ions. Several equations have been encountered, most of them have been condensed equations whereby all the reactants and products are indicated as electrically neutral molecules and compounds.
