Na^+ and NO3^- are spectator ions.
Before we decide on which ions are spectator ions, we need to look at the molecular reaction equation, complete ionic equation and net ionic equation.
The molecular reaction equation is;
AgNO3(aq) + NaCl(aq) -------> AgCl(s) + NaNO3(aq)
The complete ionic equation is;
Ag^+(aq) + NO3^-(aq) + Na^+(aq) + Cl^-(aq) -------> AgCl(s) + Na^+(aq) + NO3^-(aq)
The net ionic equation is;
Ag^+(aq) + Cl^-(aq) -------> AgCl(s)
The spectator ions are those ions that appear on both sides of the complete ionic equation. Hence, Na^+ and NO3^- are spectator ions.
