(N/A) The conductivity $(\kappa)$ of a solution is defined as the conductance of ions present in a unit volume $(1 \ cm^3)$ of the solution.
Upon dilution,the total number of ions remains the same,but the number of ions per unit volume decreases.
Since the conductivity depends directly on the concentration of ions in a unit volume,the conductivity of the solution decreases with dilution.
