MCQ
Assertion : If ${\lambda ^o}_{N{a^ + }}$ and ${\lambda ^o}_{C{l^ - }}$ are molar limiting conductivity of sodium and chloride ions respectively, then the limiting molar conductivity for sodium chloride is given by the equation :
${\Lambda ^o}_{NaCl}\, = \,{\lambda ^o}_{N{a^ + }} + {\lambda ^o}_{C{l^{\, - }}}$
Reason : This is according to Kohlrausch law of independent migration of ions

- BIf both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
- CIf the Assertion is correct but Reason is incorrect.
