NEET Chemistry Conductance MCQ Question
Type: MCQ-diagram based-Hard-Class 12
In a setup where the conductivity of an electrolytic solution is measured using platinum electrodes placed at a unit distance apart with a unit area of cross-section, what factor primarily causes the conductivity to decrease when the solution is diluted?
A
Decrease in the number of ions per unit volume
B
Increase in ion size due to solvation
C
Decrease in the mobility of ions
D
Increase in the resistivity of the solution
Correct Answer
Option A
Detailed Explanation
The decrease in conductivity upon dilution is primarily due to the reduced number of ions per unit volume that carry the current in the solution.
