Question

Assertion : Molar conductivity of a weak electrolyte at infinite dilution cannot be determined experimentally.
Reason : Kohlrausch law helps to find the molar conductivity of a weak electrolyte at infinite dilution.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

In the plot of molar conductivity versus concentration, for weak electrolyte the extrapolation to zero concentration is not possible.
