Question

Why conductivity of a electrolite solution decreases with concentration?​

Answer 1

Explanation:

With decrease in concentration, i.e., with dilution, number of ions per cm3 decreases due to large increase in volume of the solution. as conductivity is the conductance per cm3 of the solution, hence it decreases..

Hope its help...

Answer 2

With reduced concentration, conductivity decreases as the number of ions per unit volume that hold the current in a solution decrease with dilution whereas the molar conductivity of a solution increases with the decrease in concentration.
