NEET Chemistry Galvanic Cells MCQ Question
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?
E(cell) increases
E(cell) decreases
E(cell) remains unchanged
E(cell) becomes zero
Correct Answer
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.
