What are speactator ions?

Spectator ions are ions in a chemical reaction that do not participate in the actual reaction but remain in solution. They are present in both the reactants and products and do not change during the course of the reaction. Spectator ions help maintain charge balance in the solution but do not influence the overall outcome of the reaction. In net ionic equations, spectator ions are often omitted to focus on the ions and molecules that directly participate in the chemical change.
