Solution Summary

The colligative properties of solutions are examined. The given factors are associated with a particular colligative properties are examined.

Solution Preview

There are 4 colligative properties namely:
1. Vapor pressure lowering
2. Boiling point elevation
3. Freezing point depression
4. Osmotic pressure

The similarity among these 4 colligative properties is that, they all depend on the amount of solute present, and not on the identity of the solute. The necessary equations involved in colligative properties are:
1. For Vapor pressure lowering:

P = xsolvent P0
Where P = vapor pressure of solution
P0 = vapor pressure of pure solvent
xsolvent = mole fraction of the solvent

xsolvent = moles of solvent/(moles solvent + moles solute)

2. For Boiling point ...
