The osmotic pressure of equimolar solutions of BaCl2, NaCl and sucrose will be in the order:
Correct answer: D. BaCl2 > NaCl > Sucrose
- A. Sucrose > NaCl > BaCl2
- B. Sucrose > BaCl2 > NaCl
- C. NaCl > BaCl2 > Sucrose
- D. BaCl2 > NaCl > Sucrose
Explanation
Osmotic pressure is a colligative property, and the more the number of particles more the osmotic pressure. π=iCRT Hence, BaCl2>NaCl>Sucrose since the concentration is the same and i for BaCl2 is 3, NaCl is 2 and sucrose is 1.
