Question

The spectator ions in the reaction between aqueous perchloric acid and aqueous barium hydroxide are:

1) H+ and OH⁻
2) Ba₂⁺+ and ClO₄-
3) H+ and ClO₄-
4) Ba₂⁺+ and OH⁻

Answer 1

The spectator ions in the reaction between aqueous perchloric acid and aqueous barium hydroxide are H+ and OH⁻.

Step-by-step explanation:

The spectator ions in the reaction between aqueous perchloric acid and aqueous barium hydroxide are:

1. H+ and OH⁻
2. Ba²⁺+ and ClO₄⁻
3. H+ and ClO₄⁻
4. Ba²⁺+ and OH⁻

The net ionic equation for this reaction can be written as:

H+ (aq) + OH⁻ (aq) → H₂O (l)

Therefore, the correct answer is option 1) H+ and OH⁻.
