There are following three types of properties of solution:
1. Additive properties
2. Constitutive properties
3. Colligative properties
These are the properties which are due to sum of corresponding properties of individual atoms or functional groups within the molecules e.g. molecular weight.
These are the properties which depend upon the structural arrangement of atoms within the molecules for example optical properties and surface and interfacial properties.
These are the properties which depend upon the number of molecules present in solution.
Following are colligative properties of dilute solution:
1. Lowering of vapor pressure
2. Elevation of boiling point
3. Depression of freezing point
4. Osmotic pressure
