On dilution, the **molar conductivity** ($\Lambda$) of an electrolyte:
ARemains the same
BIncreases (approaches $\Lambda_0$)
CBecomes negative
DDecreases
Answer & Solution
Correct answer: B. Increases (approaches $\Lambda_0$)
Molar conductivity = conductance per mole of electrolyte. On dilution more ions are produced per mole of electrolyte (more complete dissociation, less inter-ionic interaction), so $\Lambda$ rises and asymptotes to $\Lambda_0$ at infinite dilution.
