WebIron will be reduced by reacting iron(III) oxide with carbon monoxide gas. Fe 2 O 3 (s) + 3CO (g) → 2Fe (l) + 3CO 2 (g) We can see the pattern forming in these metal oxide reduction reactions. WebBy assigning oxidation numbers, we can pick out the oxidation and reduction halves of the reaction. Aluminum is oxidized to Al 2 O 3 in this reaction, which means that Fe 2 O 3 must be the oxidizing agent. Conversely, Fe 2 O 3 is reduced to iron metal, which means that aluminum must be the reducing agent.
