Define the terms, 'osmosis' and 'osmotic pressure'. What is the advantage of using osmotic pressure as compared to other colligative properties for the determination of molar masses of solutes in solutions ?

Explanation

The process of flow of solvent from a solution through a semi-permeable membrane is called osmosis. The extra pressure that must be applied on the solution to stop the flow of solvent through the semi-permeable membrane is called osmotic pressure. The osmotic pressure method has the advantage over other methods as pressure measurement is around the room temperature and the molarity of the solution is used in place of molality.
