colligative properties of a solution

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 prop..

In colloidal systems the number of colloidal particles per litre of the sol is relatively much smaller than solute particles in a true solution. Colloidal particles are aggregates of simple molecules and colligative properties such elevation in boil..

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. Howeve..

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 membr..

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..

Heterogenous nature - Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion mediu..

It is a thermoplastic. It dissolves in suitable solvent and the solution on evaporation leaves a tough but non flexible fil..

1) It is a crystalline solid. 2) It is soluble in hot water, ethanol and ether. 3) HgCl 2 reacts with KI and forms a colorless solution known as Nessler's reagent. ..

1. It is a pale yellow powder. It has strong smell of chlorine. It is soluble in water but a clear solution is never formed due to the presence of impurities. 2. On long standing it undergoes auto-oxidation into calcium chlorate and calcium chloride. 4. On account of the formation of..
