Question

Write a net ionic equation for the reaction that occurs when aqueous solutions of hydrofluoric acid and potassium hydroxide are combined.

Answer 1

Answer:

H⁺(aq) + OH⁻(aq) ⇒ H₂O(l)

Explanation:

Let's consider the molecular equation that occurs when aqueous solutions of hydrofluoric acid and potassium hydroxide are combined. This is a neutralization reaction.

HF(aq) + KOH(aq) ⇒ KF(aq) + H₂O(l)

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

H⁺(aq) + F⁻(aq) + K⁺(aq) + OH⁻(aq) ⇒ K⁺(aq) + F⁻(aq) + H₂O(l)

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

H⁺(aq) + OH⁻(aq) ⇒ H₂O(l)
