Question: In the reaction Zn + CuSO4 → ZnSO4 + Cu, which species is reduced?

Options:

Correct Answer: Cu

Solution:

Copper (Cu) is reduced as it gains electrons from zinc.

In the reaction Zn + CuSO4 → ZnSO4 + Cu, which species is reduced?

In the reaction Zn + CuSO4 → ZnSO4 + Cu, which species is reduced?

Step 1: Identify the reactants in the reaction: Zn (zinc) and CuSO4 (copper sulfate).
Step 2: Identify the products in the reaction: ZnSO4 (zinc sulfate) and Cu (copper).
Step 3: Understand what reduction means: Reduction is when a species gains electrons.
Step 4: Determine which element is losing electrons: Zinc (Zn) is losing electrons.
Step 5: Determine which element is gaining electrons: Copper (Cu) is gaining electrons from zinc.
Step 6: Conclude that since copper gains electrons, it is the species that is reduced.

Redox Reactions – This question tests the understanding of oxidation and reduction processes in redox reactions, specifically identifying which species is reduced.
Electron Transfer – It assesses knowledge of electron transfer, where reduction involves the gain of electrons.
