Why osmotic pressure is considered as colligative property ?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Definition of Colligative Properties**: Colligative properties are properties of solutions that depend on the number of solute particles in a given amount of solvent, rather than the identity of the solute itself. 2. **Understanding Osmotic Pressure**: Osmotic pressure is the pressure required to stop the flow of solvent into a solution through a semipermeable membrane. It is a measure of the tendency of a solvent to move into a solution. ...

van't Hoff proved that osmotic pressure ( pi ) is a colligative property. For an ideal solution, osmotic pressure( pi ) is helpful to determine that molecular mass of solute using M_(B)=(W_(B)RT)/(pi.V) Relation can exxpressed by the curve (C = concentration) :
