The molar conductivity for electrolytes A and B are plotted against

C^{1/2}

as shown below. Electrolytes A and B respectively are :

Answer: (C)

A strong electrolyte's molar conductivity falls only slightly and linearly with

C

; a weak electrolyte's rises steeply near infinite dilution. Curve A drops sharply (weak), B is nearly flat (strong). Option (3): A weak, B strong.
