Q. Assertion: If

λ_{N a^{+}}^{\circ} + λ_{C l^{-}}^{\circ}

are molar limiting conductivity of the sodium and chloride ions respectively, then the limiting molar conducting for sodium chloride is given by the equation:

λ_{N a C l}^{\circ} = λ_{N a^{+}}^{\circ} + λ_{C l^{-}}^{\circ}

Reason:This is according to Kohlrausch law of independent migration of ions.
