The Correct Answer and Explanation is :
When aqueous solutions of perchloric acid (HClO₄) and barium hydroxide (Ba(OH)₂) are combined, they undergo a neutralization reaction. The reaction involves the formation of water (H₂O) and barium perchlorate (Ba(ClO₄)₂) as products. The chemical equation for this reaction can be written as:
Balanced Chemical Equation:
[
2 \text{HClO}_4 (aq) + \text{Ba(OH)}_2 (aq) \rightarrow \text{Ba(ClO}_4\text{)}_2 (aq) + 2 \text{H}_2\text{O} (l)
]
Explanation:
- Reactants:
- Perchloric Acid (HClO₄): This is a strong acid that dissociates completely in water to form H⁺ ions and ClO₄⁻ ions. In aqueous solution, it is present as HClO₄ (aq).
- Barium Hydroxide (Ba(OH)₂): This is a strong base that also dissociates completely in water to form Ba²⁺ ions and OH⁻ ions. It is represented as Ba(OH)₂ (aq) in the reaction.
- Reaction:
- The hydrogen ions (H⁺) from the perchloric acid react with the hydroxide ions (OH⁻) from the barium hydroxide to form water (H₂O), a neutral compound. This is a typical neutralization reaction, where an acid reacts with a base to produce water and a salt.
- The remaining ions, Ba²⁺ from the barium hydroxide and ClO₄⁻ from the perchloric acid, combine to form barium perchlorate (Ba(ClO₄)₂), which is a soluble salt in water.
- Products:
- Water (H₂O): Formed by the combination of hydrogen ions (H⁺) and hydroxide ions (OH⁻).
- Barium Perchlorate (Ba(ClO₄)₂): This salt is soluble in water, so it remains dissociated in the aqueous solution.
Solubility:
- HClO₄ and Ba(OH)₂ are both highly soluble in water, which is why they dissociate into ions when dissolved in water.
- Ba(ClO₄)₂ is also soluble in water and will exist in the solution as individual Ba²⁺ and ClO₄⁻ ions.
- Water (H₂O) is a liquid and does not dissociate in this context.
In summary, the reaction between aqueous perchloric acid and aqueous barium hydroxide produces barium perchlorate and water. This is a standard acid-base neutralization reaction, and the solubility of the involved compounds ensures they dissociate in water to form the final products.
