| Assertion: If \[\lambda _{N{{a}^{+}}}^{0}+\lambda _{C{{l}^{-}}}^{0}\] are molar limiting conductivity of the sodium and chloride ions respectively, then the limiting molar conducting for sodium chloride is given by the equation: \[\wedge _{NaCl}^{0}=\lambda _{N{{a}^{+}}}^{0}+\lambda _{C{{l}^{-}}}^{0}\]. |
| Reason: This is according to Kohlrausch law of independent migration of ions. |
| Read the assertion and reason carefully to mark the correct option out of the options given below: |
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
[a] According to Kohlrausch law, ?Limiting molar conductivity of an electrolyte can be represented as the sum of the individual contributions of the anion and cation of the electrolyte?.
