Question

The osmotic pressure of equimolar solutions of BaCl2, NaCl and glucose will be in the order

Answer 1

Heyyy!!
Here is your answer !
Final Result :
BaCl2>NaCl>Glucose

Now,
Osmotic Pressure is directly proportional to no. of ions produced by molecules in aquous solution .


OP (π) α i
where i is degree of dissociation.

Since ,
BaCl2 ---->Ba(2+) + 2Cl (-)
No. of ions : 3

NaCl---->Na(+) + Cl(-)
No. of ions : 2

Glucose is covalent compound and it undergoes negligible dissociation in aquous solution.

Hope,
you understand my answer and it may helps you!!!

Answer 2

Answer:

The osmotic pressure of equimolar solution of BaCl2, NaCl and glucose will be in the order-

BaCl2 > NaCl > Glucose

Since, the concentration is the same and I(degree of dissociation) for BaCl2 is 3, NaCl is 2 and glucose is 1

Osmotic pressure is a colligative property, and the more the number of particles more the osmotic pressure.

Explanation:

Osmotic pressure is a colligative property, and more the number of particles more the osmotic pressure.

Equimolar solution of glucose and Common salt are not isotonic Glucose is non electrolyte and when added in water, it does not break into ions. Nacl is an electrolyte and when added to water, it dissociates into ions of Na+ and Cl- ions completely. The two solutions will have different osmotic pressures, but same concentration.
