Assertion : If `lambda_(Na)A^(@) + lambda_(CI^(-))^(@)` are molar limiting conductivity of the sodium and chloride ions respectively, then the limiting molar conducting for sodium chloride is given by the equation: `lambda_(NaCI)^(@)=lambda_(Na)^(@)+lambda_(Cl^(-))^(@)` Reason : This is according to Kohlrausch's law of independent migration of ions.
