MHT CET 2024 Chemistry question

Which from the following concentrations of a weak electrolyte solution exhibits maximum molar conductivity?

(A)0.004 M
(B)0.002 M
(C)0.005 M
(D)0.001 MCorrect

Answer: (D)

Solution

For a weak electrolyte, the degree of dissociation increases on dilution (Ostwald's dilution law, ), so more ions are produced per mole and molar conductivity rises steeply as concentration falls, approaching
