Why does the conductivity of a solution decreases with dilution ?

Text Solution

Verified by Experts

Conductivity of an electrolyte solution depends on the number of ions present per unit volume. On dilution, the number of ions present per unit volume decreases, therefore, conductivity also decrease.
