Final answer:
The net ionic equation for the reaction is FeO(s) + 2H⁺(aq) → Fe³⁺(aq) + H₂O(l), indicating solid iron(II) oxide reacting with hydrogen ions to form aqueous iron(III) ions and water.
Step-by-step explanation:
The net ionic equation for the reaction between FeO (s) and HClO₄ (aq) is derived by first canceling out the spectator ions that do not take part in the reaction. In this case, ClO₄⁻ ions are considered spectator ions since they are present in both the reactant and product side without undergoing any change. The net ionic equation thus involves the reactants that actually change during the reaction.
The balanced molecular equation is:
FeO(s) + 2HClO₄(aq) → Fe(ClO₄)₂(aq) + H₂O(l)
Breaking down the reactants and products into ions, we have:
FeO(s) + 2H⁺(aq) + 2ClO₄⁻(aq) → Fe³⁺(aq) + 2ClO₄⁻(aq) + H₂O(l)
Removing the spectator ions, the net ionic equation will be:
FeO(s) + 2H⁺(aq) → Fe³⁺(aq) + H₂O(l)
The solid iron(II) oxide reacts with hydrogen ions to form aqueous iron(III) ions and water as products.
