What does Λ° m represent for weak electrolytes, and how is it determined?

Options

  1. AΛ° m represents molar conductivity at infinite dilution and is determined by extrapolation.
  2. BΛ° m represents molar conductivity at maximum concentration and is determined by using Kohlrausch's law.
  3. CΛ° m represents molar conductivity at zero concentration and is determined by measuring the concentration.
  4. DΛ° m represents molar conductivity at unit distance and is determined by using a conductivity cell.

Correct answer

A. Λ° m represents molar conductivity at infinite dilution and is determined by extrapolation.

Step-by-step solution

Λ° m for weak electrolytes represents molar conductivity at infinite dilution and is obtained by using Kohlrausch's law.
