### 70. Identify Spectator Ions
In the complete ionic equation:
\[ \text{Ba}^{2+}(aq) + 2 \text{I}^-(aq) + 2 \text{Na}^+(aq) + \text{SO}_4^{2-}(aq) \rightarrow \text{BaSO}_4(s) + 2 \text{I}^-(aq) + 2 \text{Na}^+(aq) \]
Spectator ions are ions that appear unchanged on both sides of the reaction equation.
