colligative properties of solutions

Dear Jayashree ramakrishna,

                    Dilute solutions containing non-volatile solute exhibit some special properties which depend only upon the no.of solute particles present in the solution irrespective of their nature.

                     The colligative properties are,

                                    1)Lowering in vapour pressure

                                    2)Elevation in boiling point

                                     3)Depression in freezing point

                                    4)Osmotic pressure

             These properties are related with one another and used for calculating the molecular masses of dissolved solutes.there are conditions

1)solution is very dilute,2)solute is non-volatile,3)solute should not undergo chemical changes with solvent.
