Limiting molar conductivity of a weak electrolyte is found using what?
AExtrapolating Lm to zero
BKohlrausch law of ions
CWheatstone bridge use
DFaraday's second law
Answer & Solution
Correct answer: B. Kohlrausch law of ions
Weak electrolyte Lm rises steeply near zero concentration, so extrapolation fails and Kohlrausch law is used.
