The molar conductivity for electrolytes A and B are plotted against C1/2 as shown below. Electrolytes A and B respectively are :
(A)Weak electrolyte, weak electrolyte
(B)Strong electrolyte, strong electrolyte
(C)Weak electrolyte, strong electrolyte✓ Correct
(D)Strong electrolyte, weak electrolyte
Answer: (C)
Solution
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.
