Colligative properties

Compreshension -I The experimental values of colligative properties of many solutes in solution resembles calculated value of colligative properties. However in same cases, the experimental value of colligative property differ widely than those obtained by calculation. Such experimental values of colligative properties are known as Abnormal values of colligative properties are : (i) Dissociation of solute : It increases the colligative properties. (ii) Association of solute : It decreases the colligative properties e.g. : Dimerisation of acetic acid in benzene If degree of dissociation of an electrolyte A_(2)B_(3) is 25% in a solvent, then

Properties such as boiling point, freezing point and vapour, pressure of a pure solvent change Propeties such as boiling point, freezing point and vapour, pressure of a pure solvent change when solute molecules are added to get homogeneous solution. These are called colligative properties. Applications of colligative properties are very useful in day-to-day life. One of its examples is the use of ethylene glycol and water mixture as anti-freezing liquid in the radiator of automobiles. A solution M is prepared by mixing athanol and water.
