Question

In the context of Fe₃+ ion, assume different possible oxidation states. What roles can Fe₃+ ion assume?

a) Fe₃+ can act as a reducing agent in certain reactions.
b) Fe₃+ can act as an oxidizing agent in certain reactions.
c) Fe₃+ can form coordination complexes with ligands.
d) Fe₃+ can participate in redox reactions as both an oxidizing and reducing agent.

Answer 1

Fe3+ ion can act as a reducing agent, an oxidizing agent, form coordination complexes, or participate in redox reactions as both an oxidizing and reducing agent.

Step-by-step explanation:

Fe3+ ion can assume different oxidation states and play various roles:

1. Fe3+ can act as a reducing agent in certain reactions, where it donates electrons to another species and is oxidized itself.
2. Fe3+ can act as an oxidizing agent in certain reactions, where it accepts electrons from another species and is reduced itself.
3. Fe3+ can form coordination complexes with ligands, where the Fe3+ ion is at the center, surrounded by ligands.
4. Fe3+ can participate in redox reactions as both an oxidizing and reducing agent, depending on the reaction conditions and the other species involved.

These different roles highlight the versatility of Fe3+ ion in chemical reactions.
