NEET Chemistry Standard Electrode Potential MCQ Question
Consider a galvanic cell where a zinc rod is immersed in a zinc sulfate solution and a copper rod is immersed in a copper sulfate solution. Which component acts as the anode in this setup, and what is its role?
Zinc rod; it undergoes oxidation and loses electrons.
Copper rod; it undergoes oxidation and loses electrons.
Zinc rod; it undergoes reduction and gains electrons.
Copper rod; it undergoes reduction and gains electrons.
Correct Answer
Detailed Explanation
In the described galvanic cell, the zinc rod acts as the anode because it undergoes oxidation, releasing electrons to the external circuit. This is consistent with the standard electrode potentials where zinc is more negative compared to copper.
