Properties such as boiling point, freezing point, and vapour pressure of a pure solvent change when solute molecules are added to get homogenous solution. These are called colligative properties.
Anwer the following questions:
i.0.1 M glucose
ii.1% urea solution
iii.0.1 M common salt
Increasing order of osmotic pressure

A

`(i) lt (iii) lt (ii)`

B

`(i) lt (ii) lt (iii)`

C

`(ii) lt (iii) lt (i)`

D

`(iii) lt (i) lt (ii)`

Text Solution

Verified by Experts

The correct Answer is:
B
Osmotic pressure is higher if `C_("effective")` is higher `(pi =iCRT)`
`:.` 0.1 m glucose `lt` 1% urea `lt` 0.1 m NaCl
