example of 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..

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 = Osmotic pressure) or but, Therefore, p = CRT wh..

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..

Sodium hydroxide is a white deliquescent solid having melting point at 591 K (318°C) It is stable towards heat It is highly soluble in water and considerable amount of heat is evolved due to the formation of a number of hydrates e.g., NaOH.H 2 O, NaOH.2H 2 O. It is also soluble in alcohol ..

It reduces many organic compounds. For example, compounds containing carbonyl group (-CO) are reduced to alcohol..

1. Calcium oxide is a white amorphous solid. 2. It is not decomposed further when heated, but produces a white brilliant light above 2732 o F. This light is called lime light. 3. It combines vigorously with water to form slaked lime (Calcium hydroxide). The process is called "Slaking of lime". It i..

Polyethylene has a low softening point of 383K and a low specific gravity of 0.22. The material is tough flexible highly insulating water resistin..
