प्रश्न

Assertion (A) : Conductivity decreases with decrease in concentration of electrolyte.

Reason (R) : Number of ions per unit volume that carry the current in a solution decreases on dilution.

पर्याय

  • Both (A) and (R) are true and (R) is the correct explanation of (A).

  • Both (A) and (R) are true, but (R) is not the correct explanation of (A).

  • (A) is true, but (R) is false.

  • (A) is false, but (R) is true.

MCQ

उत्तर

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation:

Because the number of ions per unit volume drops with dilution, the solution's current carrying capacity reduces as well. As a result, conductivity decreases with dilution.
