Question:

What is the order of osmotic pressure of equimolar solution of BaCl2, NaCl and glucose?

Options:

Glucose>NaCl>BaCl2

BaCl2 > NaCl > Glucose

NaCl > BaCl2 > glucose

NaCl > Glucose > BaCl2

Correct Answer:

BaCl2 > NaCl > Glucose

Explanation:
Osmotic pressure is a colligative property, and more the number of particles more the osmotic pressure.
 
π=iCRT
 
Hence, BaCl2>NaCl>Glucose 
since the concentration is same and i for BaCl2 is 3, NaCl is 2 and glucose is 1.
