NEET Chemistry Electrolytic Cells MCQ Question
Type: MCQ-diagram based-Medium-Class 12
Consider a Daniell cell setup where a zinc electrode is placed in a zinc sulfate solution and a copper electrode is placed in a copper sulfate solution, connected by a salt bridge. If the external voltage applied to this cell is slowly increased, what happens when the voltage reaches exactly 1.1 V?
A
The redox reaction stops completely.
B
The cell starts functioning as an electrolytic cell.
C
The cell potential increases beyond 1.1 V.
D
The cell reaction accelerates.
Correct Answer
Option A
Detailed Explanation
When the external voltage opposing the cell potential reaches 1.1 V, the reaction in the Daniell cell stops according to the description of the cell's operation under opposing voltage.
