Assuming complete ionisation, arrange the following solutions in order of increasing osmotic pressure. a) 0.5 ~m Li ₂ SO ₄ . b) 0.5 mKCl c) 0.5 ~m Al ₂ ( SO ₄ )₃ d) 0.1 ~m BaCl ₂

Options

  1. Ad b a c
  2. Bb d c a
  3. Ca d c b
  4. Dc d b a

Correct answer

A. d b a c

Step-by-step solution

Osmotic pressure is a colligative property that depends on number of particles in solution. The solution having more number of particles will have larger osmotic pressure. Hence, Al ₂ ( SO ₄ )₃ solution gives more number of particles and has the highest osmotic pressure among the given. So, the correct order of increasing osmotic pressure is d b a c
