colligative properties

Colligative Properties - Certain properties of solutions depend only on the number of particles of the solute (molecule or ions) present in definite volume of the solution and do not depend on the nature of solute. Such properties are called colligativeh..

Colloidal particles have high average molecular masses. Therefore the mole fraction of the dispersed phase is very low. Hence, in colloidal solutions the relative lowering of vapor pressure, elevation in boiling point, depression in freezing point and osmotic pressure is very low. However, osmotic..

The excess pressure that must be applied to the solution/conc.solution to prevent osmosis. fig 3.11 - Principle of measuring osmotic pressure fig 3.12 If two solutions of identical composition but different concentration are separated by a semi permeable membrane (one that permits only the solvent ..

Freezing point of a substance is defined as the temperature at which the vapor pressure of the solid form is in equilibrium with liquid form of the substance. In other words, solid and liquid forms of the substance has same vapor pressure. fig 3.10 The curves AB, BC, and A'B' are the vapor pressure..

The relation between colligative property and molecular mass of the solute is based on the following assumptions: i) The solution is dilute so that Raoult's law is obeyed. ii) The solute neither undergoes dissociation nor association in solution. When the molecular mass of unkno..

Solutions are homogeneous mixtures having great importance in our day to day life. In this chapter we have learnt the various types of solutions, the meaning of vapor pressure, Raoult's Law, Colligative Properties and Abnormal Molecular Mass..

A number of electrolytes dissociate in solution to give two or more particles (ions). Therefore, the number of solute particles, in solution of such substances is more than the expected value. Accordingly, such solutions exhibit higher values of colligative properties. Since the..
