Assertion: If lamda(Na)^(o)+lamda(Cl^(-)...

Assertion: If `lamda_(Na)^(o)+lamda_(Cl^(-))^(o)` are molar limiting conductivity of the sodium and chloride ions respectively, then the limiting molar conductivity for sodium chloride is given by the equation: `^^_(NaCl)^(o)=lamda_(Na^(+))^(o)+lamda_(Cl^(-))^(o)`.
Reason: This is according to Kohlrausch law of independent migration of ions.

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.

Text Solution

Verified by Experts

The correct Answer is:
A
According to Kohlrausch's law, "Limiting molar conductivity of an electrolyte can be represented as the sum of the individual contributions of the aion and cation of the electrolyte".
