Spectator ion

[Lizwi]

Why is NO3 called spectator ion because it can react with water to form HNO3 and turn water in OH- so the solution is neutral 

 

Thanks

Here only the cathion reaction should be considered. Instead of Nitrate, also other ions like chloride, sulfate, could be present.

A spectator ion is an ion that exists in the same form on both the reactant side and the product side of a chemical reaction.

NH₄⁺ +NO₃^- +H⁺+OH^-=H₃O⁺+NH₃+NO₃^-
