Redox Reaction

  1. Redox reactions are oxidation- reduction reactions in which the reactants change their oxidation states.
  2. Any half reaction can be broken down into half reactions one is oxidation and other is reduction.
  3. 2I-(aq)I2(s) In this reaction, two electrons are transferred and the oxidation number of Iodine(I) changes from -1 to 0.

Therefore, two electrons are transferred during this change.
