Question

Molar conductivity of a strong electrolyte at concentration c is related to its limiting value Λ°_m by the Debye-Hückel-Onsager equation

Accepted Answer

D. {'text': 'Λ_m = Λ°_m − A √c', 'label': 'D'}

1. For strong electrolytes, Λ_m decreases mildly with concentration.
2. Debye-Hückel-Onsager: Λ_m = Λ°_m − A √c, where A depends on solvent and temperature.
3. Extrapolation to zero concentration gives the limiting value Λ°_m directly.
4. Weak electrolytes follow a different law and do not extrapolate linearly.
