Questions & Step-by-Step Solutions

In the reaction 2Fe²⁺ + 2e⁻ → 2Fe, what is being reduced? (2021)
  • Step 1: Identify the reactants in the reaction, which are 2Fe²⁺ and 2e⁻.
  • Step 2: Understand that reduction is the process of gaining electrons.
  • Step 3: Notice that Fe²⁺ is gaining 2 electrons (2e⁻) in the reaction.
  • Step 4: Conclude that since Fe²⁺ is gaining electrons, it is being reduced.
  • Step 5: Recognize that the product formed is 2Fe, which is the reduced form of Fe²⁺.
  • Reduction – Reduction is the gain of electrons by a species, resulting in a decrease in oxidation state.
  • Oxidation States – Understanding oxidation states helps identify which species is being reduced or oxidized in a reaction.
