(Apex) Ions that do not participate in the reaction
spectator ions
Na+, K+,Li+, NH4 + and NO3 - are always spectator ions because they are always soluble
The spectator ions in this reaction are Na+ and NO3-. They remain unchanged on both sides of the equation and do not participate in the formation of the precipitate AgI.
To identify the spectator ions, compare the ions on both sides of the equation and look for ions that remain unchanged. In this case, Na+ and I- ions are spectator ions because they appear as both reactants and products without undergoing any chemical change. The Ba2+ and SO4^2- ions are the ions involved in the chemical reaction forming BaSO4.
Yes, the total ionic equation shows all the ions involved in the reaction, including the spectator ions. To find the net ionic equation, you can remove the spectator ions from the total ionic equation to emphasize the ions that participate in the actual chemical change.

H+ and I- are the spectator ions.
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.

The spectator ions are Ag+ and (NO3)-.
The spectator ions in this precipitation equation are K+ and NO3-. The non-spectator ions are Pb2+ and I-. They combine to form the precipitate PbI2.
Yes, the total ionic equation shows all the ions involved in the reaction, including the spectator ions. To find the net ionic equation, you can remove the spectator ions from the total ionic equation to emphasize the ions that participate in the actual chemical change.
Spectator ions can be recovered from a chemical reaction by performing a precipitation reaction, where a soluble compound is added to the solution to form an insoluble salt that includes the spectator ions. After the precipitation occurs, the mixture can be filtered to separate the solid precipitate from the liquid. The filtrate can then be analyzed to confirm the presence of the recovered spectator ions. Additionally, techniques like evaporation or crystallization may be used to isolate the spectator ions for further study.
Spectator ions, in a chemical reaction, are ions that don't take part in the overall reaction. For instance, consider the following reaction:Pb2+ (aq) + 2 NO3 (aq) + 2 K+(aq) + 2 I-(aq) ---> PbI2(s) + 2 K+(aq) + 2 NO3-(aq)The bolded and italicized compounds are spectator ions. They do not play an active role in the reaction. So, when these spectator ions are removed, we end up with a net ionic equation:Pb2+(aq) + 2 I-(aq) ---> PbI2(s)Source: College student in Chemistry, wrote these examples out of the book.
The spectator ions in the reaction between silver sulfate and barium nitrate are nitrate (NO3-) ions and sulfate (SO4^2-) ions. These ions do not participate in the formation of the precipitate (barium sulfate) and remain unchanged throughout the reaction.
