Given below are two statements
Assertion (A): Conductivity of an electrolyte decreases on dilution
Reason (R): On dilution number of ions per unit volume increases
The correct answer is
Both (A) and (R) are correct and (R) is the correct explanation of $(A)$
Both (A) and (R) are correct and (R) is not the correct explanation of $(A)$
(A) is correct but (R) is not correct
(A) is not correct but (R) is correct
Solution
Conductivity $(K)=$ Number of ions dissolved in unit
volume of the solution.
Thus, upon dilution, the number of ions per unit volume decreases because of which conductivity decreases.
Thus, Assertion (A) is correct but Reason (R) is not correct.
