Redox Reactions

2FeCl2(s) + Cl2(g) → 2FeCl3(s). The reducing agent in the reaction above is

  1. A.FeCl2
  2. B.Cl2
  3. C.FeCl3
  4. D.Fe
Show the answer and explanation

Answer: A (FeCl2)

Explanation

Iron goes from +2 in FeCl2 to +3 in FeCl3, so FeCl2 loses electrons (is oxidized) and is the reducing agent.
