For a weak electrolyte, a plot of a (degree of ionisation)vs 1/C gives

A)  a straight line                   

B)  a parabola

C)  a hyperbola         

D)  an exponential curve

Correct Answer: B

Solution :

                Degree of ionisation increases with increase on dilution. At infinite dilution, degree of ionisation of weak electrolytes becomes 1 and plot becomes like a parabola.
