Calculation of the degree of Association
Calculation of the degree of Association : The fraction of the total number of solute molecules which exist in the form of associated molecule is called degree of association.

Calculation of the degree of Dissociation
Calculation of the degree of Dissociation : The fraction of the total number of electrolyte molecules that undergoes dissociation is called degree of dissociation.
Read moreAbnormal molecular mass and Van’t Hoff factor
Abnormal molecular mass and Van’t Hoff factor : When the molecular mass of a substance determined by studying any of the colligative properties comes out to be different than the theoretically expected value.
Read moreOsmotic Pressure
Osmotic pressure : It can be defined as the additional pressure applied on the solution to prevent the entry of the solvent into the solution through semi-permeable membrane. It is represented by ‘π’.
Read moreDepression in freezing point
Depression in freezing point : Freezing point of a substance is the temperature at which the solid and liquid forms of the substance have same vapour pressure.
Read moreElevation in boiling point
Elevation in boiling point : The boiling point of liquid is the temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure.
Read moreRelative lowering of vapour pressure
Relative lowering of vapour pressure : The vapour pressure of solvent in solution is less than that of pure solvent. This is because of non-volatile solute occupy some surface area; hence the vapour pressure decrease.

Colligative Properties are those properties of ideal solutions which depend only on the number of solute particles but do not depend on the nature of solute are called colligative properties.
