ZnF₂ (s) ⇌ Zn²⁺ (aq) + 2F⁻ (aq)

Here's what it means:

* ZnF₂ (s) represents solid zinc fluoride.

* Zn²⁺ (aq) represents the zinc cation in aqueous solution.

* 2F⁻ (aq) represents two fluoride anions in aqueous solution.

* ⇌ indicates an equilibrium reaction. This means that the reaction can proceed in both directions, with the solid dissolving into ions and the ions recombining to form the solid.

Explanation:

When zinc fluoride (ZnF₂) dissolves in water, it breaks apart into its constituent ions, forming zinc cations (Zn²⁺) and fluoride anions (F⁻). The equation shows that one mole of ZnF₂ produces one mole of Zn²⁺ ions and two moles of F⁻ ions.
