Answer:
Fe is the reducing agent while oxygen is the oxidizing agent
Step-by-step explanation:
- In the reaction above Iron loses electrons to form iron ions and this is called oxidation. Therefore, iron is the reducing agent which loses electrons and becomes oxidized to form Iron(iii) ion.
- On the other hand, Oxygen gains or accepts electrons and therefore, it undergoes reduction. This means oxygen is the reducing agent that accepts electrons and becomes reduced to oxygen ion.
