Question

which ions, if any, are spectator ions in the reaction agno₃ (aq) + nacl (aq) →agcl (s) + nano₃ (aq)? express your answers as ion separated by a comma.

Explanation:

Step1: Write the complete ionic equation

The reactants $AgNO_3(aq)$ and $NaCl(aq)$ dissociate. $AgNO_3(aq)=Ag^{+}(aq)+NO_3^{-}(aq)$ and $NaCl(aq) = Na^{+}(aq)+Cl^{-}(aq)$. The products: $AgCl(s)$ does not dissociate (it is a precipitate) and $NaNO_3(aq)=Na^{+}(aq)+NO_3^{-}(aq)$. So the complete - ionic equation is $Ag^{+}(aq)+NO_3^{-}(aq)+Na^{+}(aq)+Cl^{-}(aq)=AgCl(s)+Na^{+}(aq)+NO_3^{-}(aq)$.

Step2: Identify spectator ions

Spectator ions are those that appear on both sides of the complete - ionic equation. Here, $Na^{+}(aq)$ and $NO_3^{-}(aq)$ are present on both sides.

Answer:

$Na^{+},NO_3^{-}$
