As we learned

 

Osmotic Pressure -

Osmotic Pressure  (\pi) is excess pressure developed on solution side due to osmosis.

-

 

 Osmotic pressure method is especially suitable for the determination of molecular masses of macromolecules such as protein & polymer because for these substances the value of other colligative properties such as elevation in boiling point or depression in freezing point are too small to be measured on the other hand osmotic pressure of such substances are measurable.

 


Option 1)

Relative lowering of vapour pressure

Option 2)

Elevation of boiling point

Option 3)

Depression in freezing point

Option 4)

Osmotic pressure
