Questions & Step-by-Step Solutions

In the reaction 2Fe²⁺ + Cl2 → 2Fe³⁺ + 2Cl⁻, what is being oxidized? (2021)
  • Step 1: Identify the reactants in the reaction: 2Fe²⁺ and Cl2.
  • Step 2: Determine the oxidation states of the elements in the reactants.
  • Step 3: Notice that Fe²⁺ has an oxidation state of +2.
  • Step 4: Observe that in the products, Fe³⁺ has an oxidation state of +3.
  • Step 5: Understand that oxidation is the process of losing electrons.
  • Step 6: Since Fe²⁺ goes from +2 to +3, it loses one electron.
  • Step 7: Conclude that Fe²⁺ is being oxidized to Fe³⁺.
