Question

Define limiting molar conductivity. Why conductivity of an electrolyte solution decreases with the decrease in concentration?

Answer 1

Limiting Molar conductivity is the conductivity of the solution at infinite dilution, i.e. all the ions have dissociated or the ions are farther apart.

Conductivity of electrolyte decreases with decrease in concentration as number of ions per unit cm of surface area decreases upon dilution.
