In the reaction 2Fe²⁺ + Cl2 → 2Fe³⁺ + 2Cl⁻, which element is oxidized? (2021)

In the reaction 2Fe²⁺ + Cl2 → 2Fe³⁺ + 2Cl⁻, which element is oxidized? (2021)

Step 1: Identify the reactants and products in the reaction: 2Fe²⁺ + Cl2 → 2Fe³⁺ + 2Cl⁻.
Step 2: Look at the oxidation states of iron (Fe) in the reactants and products.
Step 3: In the reactants, iron (Fe) has an oxidation state of +2 (Fe²⁺).
Step 4: In the products, iron (Fe) has an oxidation state of +3 (Fe³⁺).
Step 5: Determine if the oxidation state of iron increased or decreased. It increased from +2 to +3.
Step 6: Conclude that since the oxidation state of iron increased, iron (Fe) is oxidized in this reaction.
