NEET Chemistry Electrolytic Cells MCQ Question
In a Daniell cell, which of the following statements about the electrochemical processes and their effects on the cell potential is correct?
The cell potential increases with an increase in Cu²⁺ concentration and decreases with an increase in Zn²⁺ concentration.
The cell potential remains constant regardless of the concentrations of Cu²⁺ and Zn²⁺ ions.
The concentration of Zn²⁺ ions has no effect on the cell potential.
The cell potential can only be measured when the concentrations of both ions are equal.
Correct Answer
Detailed Explanation
According to the NCERT context, the cell potential of a Daniell cell increases with an increase in the concentration of Cu²⁺ ions and decreases with a decrease in the concentration of Zn²⁺ ions, affirming the relationship between concentration and cell potential.
