Question
Which species functions as the oxidizing agent in thefollowing oxidation-reduction reaction?Zn(s) + Pt2+(aq) Pt(s) + Zn2+(aq)A. Pt(s)B. Zn2+(aq)C. Pt2+(aq)D. Zn(s)E. None of these, as this is not a redox reaction.12
Solution
In a redox reaction, the oxidizing agent is the species that is reduced, meaning it gains electrons.
In the given reaction: Zn(s) + Pt2+(aq) → Pt(s) + Zn2+(aq)
Zn(s) is oxidized to Zn2+(aq) because it loses electrons.
Pt2+(aq) is reduced to Pt(s) because it gains the electrons that Zn(s) lost.
Therefore, Pt2+(aq) is the oxidizing agent in this reaction.
So, the answer is C. Pt2+(aq).
