How is Λ° m calculated for weak electrolytes?

Options

  1. ABy using the equation Λ m = Λ° m - A c1/2
  2. BBy extrapolation of Lm to zero concentration
  3. CBy using the Kohlrausch law of independent migration of ions
  4. DBy measuring the conductivity at infinite dilution

Correct answer

C. By using the Kohlrausch law of independent migration of ions

Step-by-step solution

For weak electrolytes, Λ° m is obtained by using Kohlrausch's law of independent migration of ions.
