Osmotic Pressure

The O.P. (Osmotic Pressure) of equimolar solution of Urea, BaCl2 and AlCl3, will be in the order:
(a) AlCl3 > BaCl2 > Urea  (b) BaCl2 > AlCl3 > Urea  (c) Urea > BaCl2 > AlCl3  (d) BaCl2 > Urea > AlCl3       

Answer: (a) The particle come of AlCl3 solution will be maximum due to ionisation less in BaCl2 and minimum in urea.

AlCl3 → Al3+ + 3Cl- = 4
BaCl2 → Ba2+ + 2Cl- = 3     

More the number of particles in solution more is the osmotic pressure a colligative properties.
