osmotic pressure as a colligative property wit problems

Colligative Properties - Osmotic Pressure - 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 comp..

For a given solvent the osmotic pressure depends only upon the molar concentration of solute but does not depend on its nature. The following relation relates osmotic pressure to number of moles of solute: p V=nRT Van't Hoff 's solution equation ( p = Os..

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..

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 colligative properties. A few colliga..

. This is due to the reason that for these substances the values of other colligative properties such as elevation in boiling point or depression in freezing point are too small to be measured. On the other hand, osmotic pressure of such substances are measur..

Colligative Properties - Depression in Freezing Point - 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 substanc..

The relative lowering of vapor pressure is a colligative property as it depends only on the concentration of the solute and it is independent of its nature. Consider a binary solution consisting of non volatile solute in a volatile solvent. The vapor pressure..

Tonicity of Solutions - Cell walls in living organisms are seldom perfectly semipermeable. Usually they permit passage to some of the simpler substances and then these substances fail to register an osmotic pressure contribution on the cell walls. The reduced osmotic h..

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..
