Question

On dilution of a solution, its specific conductance ______ while its equivalent conductance ______.

Answer 1

On dilution of a solution, its specific conductance decreases while its equivalent conductance increases.

Explanation:

Specific conductance (κ) depends on the number of ions per unit volume. On dilution, ion concentration per cm³ decreases, so specific conductance decreases. Equivalent conductance (Λ_eq​) is the conductance of all ions from one gram equivalent of electrolyte. On dilution, ionic mobility increases (less inter-ionic interaction), so Λ_eq increases.
