276225 Assertion : If $\lambda_{\mathrm{Na}^{+}}^{\circ}$ and $\lambda_{\mathrm{Cr}}^{\circ}$ are molar limiting conductivity of sodium and chloride ions respectively, then the limiting molar conductivity for sodium chloride is given by the equation:
$\lambda_{\mathrm{NaCl}}^{\circ}=\lambda_{\mathrm{Na}}^{\circ}+\lambda_{\mathrm{Cr}}^{\circ}$
Reason : This is according to Kohlrausch law of independent migration of ions.

1 If both Assertion and Reason are correct and the Reason is the correct explanation of Assertion.
2 If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
3 If Assertion is correct but Reason is in correct.
4 If both the Assertion and Reason are incorrect.
