What is the correct sequence of osmotic pressure of 0.01 M aq. Solution of :
(1)`Al_(2)(SO_(4))_(3) " " (2) Na_(3)PO_(4)`
(3) `BaCl_(2)" "` (4) Glucose

A

`pi_(4)gtpi_(2)gtpi_(3)gtpi_(1)`

B

`pi_(3)gtpi_(4)gtpi_(2)gtpi_(1)`

C

`pi_(3)gtpi_(4)gtpi_(1)gtpi_(2)`

D

`pi_(1)gtpi_(2)gtpi_(3)gtpi_(4)`

Text Solution

Verified by Experts

The correct Answer is:
4
`pi=iCRT," "i=5` for `Al_(2)(SO_(4))_(3)`.
`i=4` for `Na_(3)PO_(4)`
`i=3` for `BaCl_(2),i=1` for glucose
So osmotic pressure of `:`
Glucose `lt BaCl_(2) lt Na_(3)PO_(4) lt Al_(2)(SO_(4))_(3)`
