L oss E lectrons → O xidation → Reducing Agent Strong reducing agents are weak oxidizing agents. Sodium, hydrogen, and lithium are examples of strong oxidizing agents. While weak reducing agents cannot lose electrons easily. Fluorine, chlorine, iron etc. are weak reducing agents Of these species—H 2 O 2 (aq), Zn(s), I − (aq), Sn 2 + (aq), identify which is the strongest reducing agent in aqueous solution and thus the best candidate for a commercial product. From the data in Table \(\PageIndex{1}\), suggest an alternative reducing agent that is readily available, inexpensive, and possibly more effective at removing. The permanganate ion removes electrons from oxalic acid molecules and thereby oxidizes the oxalic acid. Thus, the MnO 4-ion acts as an oxidizing agent in this reaction. Oxalic acid, on the other hand, is a reducing agent in this reaction. By giving up electrons, it reduces the MnO 4-ion to Mn 2+.. Atoms, ions, and molecules that have an unusually large affinity for electrons tend to be good.

Why is fluorine gas the strongest oxidizing agent and fluoride ion is the weakest reducing agent?
