Question

Reason
On dilution number of ions per unit volume decreases.
Assertion
Conductivity of all electrolytes decreases on dilution.
Conductivity of all electrolytes decreases on dilution.

Answer 1

Correct option is A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Conductivity always decreases with the decrease in concentration both, for weak and strong electrolytes. This can be explained by the fact that the number of ions per unit volume that carry the current in a solution decreases on dilution.
