To determine the net ionic equation for the given reaction:
[tex]\[ 2 H^+ + SO_4^{2-} + Ca^{2+} + 2 I^- \rightarrow CaSO_4 + 2 H^+ + 2 I^- \][/tex]
we need to follow these steps:
1. Identify the spectator ions: Spectator ions are ions that do not participate in the actual reaction and remain unchanged on both sides of the equation. In this reaction, the ions [tex]\( 2 H^+ \)[/tex] and [tex]\( 2 I^- \)[/tex] appear on both sides of the equation without any change.
2. Remove the spectator ions: By eliminating [tex]\( 2 H^+ \)[/tex] and [tex]\( 2 I^- \)[/tex] from both sides of the equation, we simplify the reaction to:
[tex]\[ SO_4^{2-} + Ca^{2+} \rightarrow CaSO_4 \][/tex]
3. Write the net ionic equation: The simplified equation from which spectator ions have been removed represents the net ionic equation.
Thus, the net ionic equation for the given reaction is:
[tex]\[ SO_4^{2-} + Ca^{2+} \rightarrow CaSO_4 \][/tex]
Reviewing the provided options:
- Option A: Incorrect, it doesn't show the net ionic equation.
- Option B: Correct, it precisely matches our simplified reaction.
- Option C: Incorrect, it includes spectator ions.
- Option D: Incorrect, it includes spectator ions.
Therefore, the correct answer is:
[tex]\[ \boxed{2} \][/tex]
Represented as option B:
[tex]\[ SO_4^{2-} + Ca^{2+} \rightarrow CaSO_4 \][/tex]
[tex]\[ 2 H^+ + SO_4^{2-} + Ca^{2+} + 2 I^- \rightarrow CaSO_4 + 2 H^+ + 2 I^- \][/tex]
