Assertion : Molar conductivity of a weak electrolyte at infinite...

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.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion.

Step-by-step solution

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