Answer:
Ksp = [Mg₂⁺][F⁻]²
Explanation:
Ksp is the equilibrium constant for a solid dissolving in an aqueous solution. The equilibrium constant for a reaction is always products over reactants.
MgF₂ (s) ⇒ Mg₂⁺(aq) + 2F⁻(aq)
The equilibrium constant would be K = [Mg₂⁺][F⁻]². Since MgF₂ is solid, it is not included in the equilibrium expression.
Therefore, Ksp would be the same as the equilibrium constant.
Ksp = [Mg₂⁺][F⁻]²
Hope this helps.
