Question

Specific conductance of a solution decreases upon dilution. Why?

Answer 1

Specific conductance (κ) of a solution decreases on dilution because it represents the conductance of a unit volume of the solution. When a solution is diluted, the concentration of ions per unit volume decreases, which lowers the solution’s ability to conduct electricity. Even though molar conductivity increases, the conductance per unit volume of the solution decreases.
