Spectator ions do not actively participate in the chemical reaction but remain in the solution unchanged. They are components of the reaction mixture that do not react with the other ions present. An example is the sodium ion in a reaction involving silver nitrate and sodium chloride, where sodium remains in solution while silver chloride precipitates out.
A complete ionic equation shows all ions present in a chemical reaction, including spectator ions that do not participate in the reaction. It separates all aqueous compounds into their respective cations and anions.
The spectator ions in the reaction between copper (II) chloride (CuCl2) and aqueous ammonium phosphate ((NH4)3PO4) are Cl- and NH4+. These ions do not participate in the chemical reaction and remain unchanged in the solution.
(Apex) Ions that do not participate in the reaction
Spectator ions are ions that do not participate in a chemical reaction and remain unchanged before and after the reaction. They are often found in solution as part of ionic compounds and may be written explicitly in chemical equations to represent their presence without being involved in the actual reaction.
In the reaction 2KOH + H2SO4 -> 2H2O + K2SO4, the spectator ions are K+ and SO4^2-. These ions do not participate in the chemical reaction i.e., they remain unchanged before and after the reaction.
The spectator ions in this reaction are perchlorate (ClO4-) and barium (Ba2+). These ions do not participate in the reaction and remain in the solution before and after the reaction takes place.

(Apex) Ions that do not participate in the reaction
called spectator ions. These ions do not participate in the actual chemical reaction and remain unchanged throughout the process. They are typically found in ionic compounds that dissociate in solution.
The first step in writing a net ionic equation is to write down the balanced chemical equation for the reaction. From there, you can identify the aqueous ionic compounds and break them down into their respective ions. The net ionic equation will only include the ions that participate in the reaction.

The spectator ions in this reaction are Cl- and Li+. They are present on both sides of the reaction unchanged and do not participate in the main chemical reaction.

A net ionic equation is a chemical equation that shows only the ions that participate in a reaction, excluding spectator ions that do not undergo a chemical change. By focusing on the ions involved in the reaction, net ionic equations provide a clearer representation of the key chemical process taking place.
A net ionic equation includes only the ions and molecules that participate in the chemical reaction. Spectator ions, which do not participate in the reaction, are not included in the net ionic equation. The components included are the reactant ions that form the products of the reaction.
