Question

Hydrochloric acid dissolves solid aluminum hydroxide. What is the net ionic equation of this reaction

Answer 1

Answer:

3 H⁺(aq) + 3 OH⁻(aq) ⇒ 3 H₂O(l)

Explanation:

Let's consider the molecular equation for the neutralization between hydrochloric acid and aluminum hydroxide.

3 HCl(aq) + Al(OH)₃(aq) ⇒ AlCl₃(aq) + 3 H₂O(l)

The complete ionic equation includes all the ions and the molecular compounds.

3 H⁺(aq) + 3 Cl⁻(aq) + Al³⁺(aq) + 3 OH⁻(aq) ⇒ Al³⁺(aq) + 3 Cl⁻(aq) + 3 H₂O(l)

The net ionic equation includes only the ions that participate in the reaction and the molecular compounds.

3 H⁺(aq) + 3 OH⁻(aq) ⇒ 3 H₂O(l)
