(NH4)3PO4 +
3CaCl2----->Ca3(PO4)2+
6NH4Cl
Here NH4+ and Cl- are spectator ions.
Spectator ions are ions that are present in the reaction
mixture, but do not
participate in it. They will always have the same
exact
formula and charge and also physical state.
Here NH4+ and Cl- have same oxidation state on both sides of reaction .In case of redox reactions spectator ions will have same oxidation state on reactant side and product side.
Thank you

In many chemical reactions of two or more compounds, ions are present in the solution that do not participate in the reaction. These ions, known as spectator ions, can be removed from the chemical equation describing the reaction. A chemical equation that has the spectator ions removed is known as a net ionic equation. Reactions between ionic compounds often result in the precipitation of an insoluble compound. Spectator ions and precipitation products of a chemical reaction can be predicted by...
