Question

When aqueous solutions of potassium fluoride and hydrochloric acid are mixed, an aqueous solution of potassium chloride and hydrofluoric acid results. Write the net ionic equation for the reaction.

Answer 1

K⁺ (aq) + F⁻ (aq) + H⁺ (aq) + Cl⁻ (aq) → KCl (aq) + H⁺ (aq) + F⁻ (aq)

Step-by-step explanation:

KF (aq) + HCl (aq) → KCl (aq) + HF (aq)

KF (aq) → K⁺ (aq) + F⁻ (aq)

HCl (aq) → H⁺ (aq) + Cl⁻ (aq)

KCl (aq) → K⁺ (aq) + Cl⁻ (aq)

HF (aq) → H⁺ (aq) + F⁻ (aq)
