Question
- A. Cu^2+
- B. Zn
- C. SO4^2-
- D. H2O
Answer
The correct option is Zn.
Explanation
In this reaction, zinc (Zn) is oxidized to Zn^2+, meaning it loses electrons. Therefore, it acts as a reducing agent by donating electrons to Cu^2+, which is reduced to Cu.
Common mistake
Misidentifying Oxidation and Reduction
Students often confuse oxidation with reduction, thinking that both involve an increase in oxidation state.
Remember that oxidation is defined as an increase in oxidation state, while reduction is a decrease. For example, in the reaction of zinc with copper sulfate, zinc is oxidized (its oxidation state increases from 0 to +2) and copper is reduced (its oxidation state decreases from +2 to 0).
