Answer:
2HC₂H₃O₂(aq) + Mg(OH)₂(s)⟶ Mg²⁺(aq) + 2C₂H₃O₂⁻(aq) + 2H₂O(ℓ)
Explanation:
An ionic equation uses the symbols (aq) [aqueous] to indicate molecules and ions that are soluble in water, (s) [solid] to indicate insoluble solids, and (ℓ) to indicate substances (usually water) in the liquid state.
This reaction is an acid-base neutralization, in which a weak acid reacts with an insoluble base to form water and a soluble salt.
1. Molecular equation
2HC₂H₃O₂(aq) + Mg(OH)₂(s) ⟶ Mg(C₂H₃O₂)₂(aq) + 2H₂O(ℓ)
2. Ionic equation
Magnesium acetate is a soluble ionic compound, so we write it as hydrated ions.
2HC₂H₃O₂(aq) + Mg(OH)₂(s)⟶ Mg²⁺(aq) + 2C₂H₃O₂⁻(aq) + 2H₂O(ℓ)
