Multiple Choice

Identify the net ionic equation for the following equation and the spectator ion, if there is one. (Hint: Write the complete ionic equation to determine the net ionic equation)

FeO(s) + 2HClO₄(aq) 🡪 H₂O(l) + Fe(ClO₄)₂(aq)

• FeO(s) + 2H⁺(aq) + 2ClO₄^-(aq) → H₂O(l) + Fe²⁺(aq) + 2ClO₄^-(aq)

  no spectator ion

• FeO(s) + 2H⁺(aq) + 2ClO₄^-(aq) → H₂O(l) + Fe²⁺(aq) + 2ClO₄^-(aq)

  ClO₄^- is a spectator ion

• FeO(s) + 2H⁺(aq) → H₂O(l) + Fe²⁺(aq)

  ClO₄^- is a spectator ion

• FeO(s) + 2HClO₄(aq) → H₂O(l) + Fe(ClO₄)₂(aq)

  no spectator ion
