Spectator ions are ions that are present during the reaction but are unchanged by the reaction, and so are present in the same state on both sides of the equation. Write the net ionic equation when aqueous solutions of copper(II) chloride and potassium phosphate are mixed, a precipitate of copper(II) phosphate is formed. In the representation of a chemical reaction, the net ionic equation always shields the existence of the spectator ions, although it has been involved in the initial reaction.Hence, the total ionic reaction always exists as different from the net reaction. This way, when you cross out spectator ions at Step 3, you cross out equivalent numbers of ions. A spectator ion is a charged atom or group of atoms in a chemical reaction that does not undergo a chemical change or change state when the reaction takes place. Answer (1 of 4): It depends on what kind of reaction you're looking at. From the solubility rules, you know both sodium chloride and copper sulfate dissociate into their ions in water. When an atom/molecule gains negatively charged electron(s), a negative ion is formed. Consider a precipitation reaction between two compounds KOH and HNO3 as represented below: KOH(aq) + HNO3 KNO3(aq) + H2O(l)K+(aq) + OH(aq) + H+(aq) + NO3(aq) K+(aq) + NO3(aq) + H2O(l).
