    Fe²⁺ (aq) + 2OH⁻ (aq) → Fe (OH) ₂ (s)

    Explanation:

    To determine the reaction, we define the reactants:

    FeCl₂, NaOH

    We dissociate them:

    FeCl₂ (aq) → Fe²⁺ (aq) + 2Cl⁻ (aq)

    NaOH (aq) → Na⁺ (aq) + OH⁻ (aq)

    Salts from chloride are soluble, except for Ag⁺, Pb²⁺, Hg₂²⁺, Cu⁺

    The OH⁻ and the Fe²⁺ bonds to make a precipitate.

    So, the molecular complete equation is:

    FeCl₂ (aq) + 2NaOH (aq) → Fe (OH) ₂ (s) ↓ + 2NaCl (aq)

    When we dissociate the elements, we get the net ionic equation but as we produced an state's change, the compound stays the same.

    We cancel the spectators ions (the ones, that are repeated)

    Fe²⁺ (aq) + 2Cl⁻ (aq) + 2Na⁺ (aq) + 2OH⁻ (aq) → Fe (OH) ₂ (s) + 2Na⁺ (aq) + 2Cl⁻ (aq)

    Fe²⁺ (aq) + 2OH⁻ (aq) → Fe (OH) ₂ (s)
