Question

Assertion (A) Conductivity of all electrolytes decreases on dilution.
Reason(R) On dilution number of ions per unit volume decreases.
A. Both assertion and reason are true and the reason is the correct explanation of assertion.
B. Both assertion and reason are true and reason is not the correct explanation of assertion.
C. Assertion is true but the reason is false.
D. Both assertion and reason are false.

Answer 1

Correct Answer -
Both assertion and reason are correct and reason is the correct explanantion of assertion. Since, conductiy depdns upon number of ions per unit volume.Therefore the conductivity of all electrolysis decreases on dilution due to decrease in number of ions per unit volume.
