Electron Transfer in Oxidation-Reduction Reactions

Outline the role of electron transfer in oxidation-reduction reactions

  • Oxidation: The process of electron loss.
  • Reduction: The process of electron gain.
  • Oxidation and reduction always occur simultaneously.
  • Oxidation-Reduction Reaction: Also known as a redox reaction, a reaction that involves both oxidation and reduction, and thus involves electron transfer.
  • Electron transfer in oxidation-reduction reactions can occur:
    • Directly between reactants.
    • From the site of oxidation through a conductor to the site of reduction.
  • The reactants in oxidation-reduction reactions are known as:
    • Reductant: The species being oxidised.
    • Oxidant: The species being reduced.
