Aqueous sodium hydroxide is added to iron(II) sulfate solution until no further change is seen. A green precipitate forms. Which ionic equation represents this reaction?
- Fe²⁺(aq) + 2OH⁻(aq) → Fe(OH)₂(s)
- Fe²⁺(aq) + 2OH⁻(aq) → FeO(s) + H₂O(l)
- Fe²⁺(aq) + OH⁻(aq) → FeOH⁺(aq)
- Fe²⁺(aq) + 2H₂O(l) → Fe(OH)₂(s) + 2H⁺(aq)
