Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
NaCl is ionic salt and completely dissociate into ions when added into water and form aqueous solution of ions,
and we have,
$N a C l \to N a^{+} + C l^{-}$ and ions get hydrated by the water molecules.

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.
