Question

For a strong electrolyte, as concentration decreases (dilution increases), molar conductivity:
  1. A
    Increases, approaching Λ°m
    Correct
  2. B
    Decreases
  3. C
    Remains constant
  4. D
    First increases then decreases

Correct answer

Increases, approaching Λ°m

Explanation

Molar conductivity Λm increases on dilution and approaches the limiting molar conductivity Λ°m at infinite dilution (Debye-Hückel-Onsager equation: Λm = Λ°m − b√c).
