Question

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

Answer 1

Answer: (B)

a parabola

Answer 2

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.
