Answer:
The molecular equation for the reaction between barium hydroxide and perchloric acid is:
Ba(OH)₂ (aq) + 2 HClO₄ (aq) → Ba(ClO₄)₂ (aq) + 2 H₂O (l)
To write the net ionic equation, we need to first identify the spectator ions, which are ions that do not participate in the reaction and remain in the same form on both the reactant and product sides of the equation.
In this case, the spectator ions are the Ba²⁺ and ClO₄⁻ ions, which are present on both sides of the equation. Therefore, we can eliminate them from the net ionic equation:
Ba²⁺ (aq) + 2 OH⁻ (aq) + 2 H⁺ (aq) + 2 ClO₄⁻ (aq) → 2 H₂O (l) + 2 ClO₄⁻ (aq)
The net ionic equation for the reaction is:
Ba²⁺ (aq) + 2 OH⁻ (aq) + 2 H⁺ (aq) → 2 H₂O (l)
In this net ionic equation, we only include the ions and molecules that participate in the reaction, which are the Ba²⁺ ion, the OH⁻ ion, the H⁺ ion, and water (H₂O). The net ionic equation shows that barium hydroxide and perchloric acid react to form water as the only product, while the Ba²⁺ and ClO₄⁻ ions do not participate in the reaction.
