  • Balance the redox reaction and determine the oxidizing/reducing agent in each reaction.
  • Recall that the oxidizing agent is the one being reduced (GER-OA = Gain electrons, reduced- Oxidizing agent) while reducing agent is the one being oxidized (LEO-RA = Lose electrons, oxidized – Reducing agent)

PART A

We are being asked to balance the given oxidation-reduction reaction. The reaction is under acidic conditionsBalance the redox reaction under acidic conditions:
