Type: MCQ-numerical-Easy-Class 12
What is the effect on the cell potential E(cell) when the concentration of Cu2+ ions is doubled while the concentration of Zn2+ ions remains constant in a Daniell cell?
A
E(cell) increases
B
E(cell) decreases
C
E(cell) remains unchanged
D
E(cell) becomes zero
Correct Answer
Option A
Detailed Explanation
The cell potential E(cell) increases with an increase in the concentration of Cu2+ ions according to equation (2.11) in the NCERT context, as the term ln([Zn2+]/[Cu2+]) decreases.
