State Kohlrausch’s law of independent migration of ions.

“Limiting molar conductivity of an electrolyte is the sum of individual limiting molar conductivities of cation & anion of that electrolyte” ${\mathrm{\Lambda }}_{\mathrm{m}}^0={\mathrm{\lambda }}_0^{+}+{\mathrm{\lambda }}_0^{-}$
Where ${\mathrm{\lambda }}_0^{+},{\mathrm{\lambda }}_0$ are ionic conductances at infinite dilution
eg : ${\mathrm{\Lambda }}_{\mathrm{m}\left(\mathrm{NaCl}\right)}^0={\mathrm{\lambda }}_{\mathrm{m}(\mathrm{Na}}^0+{\mathrm{\lambda }}_{\mathrm{m}\left(\mathrm{Cl}\right)}^0$
