What is the correct sequence of osmotic pressure of `0.01 M aq.` solution of `:`
`(a) Al_(2)(SO_(4))_(3)" "(b) Na_(3)PO_(4)" "(c ) BaCl_(2)" " (d) Gluc ose`

Options

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)`

Answer

4

Explanation

`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)`
