In a colloidal state, the particle size of he dispersed phase ranges between 10^(3) to 10^(6) pm and the colloidal sol is of heterogeneous nature. Depending upon the ease with which these sols are formed, the colloidal sols are cassified as lyophilic and lyophobic. THe stability of a colloidal sol is due to the presence of charge on the sol particles and the neutralisation of the same is known as coagulation or precipitation. The coagulationg power of the active ions of he electrolytes can be compared with the help of Hardy-Schulze Law. The protecting power of the lyophilic sols can be compared with the help of gold number. Lesser the value of gold number, more will be the protecting power of the lyophilic sol [AgI]I^(-) colloidal sol can be coagulated by the addition of a suitable action. 1 mol of [AgI]I^(-) required mole of AgNO_(3), Pb (NO_(3))_(2) and Fe(NO_(3))_(3) as:

Which is not the characteristic of hydrophobic sols? a. They are highly susceptible to coagulation by addition of electrolytes. b. They have nearly the same surface tension and viscosity as that of dispersion medium. c. Their stability is due to both electric charge and salvation of the particles. d. Sol particles can be seen under ultramicroscope.

Read the passage given below and answer the following questions: Some colloids are stable by their nature, i.e., gels, alloys, and solid foams. Gelatin and jellies are two common examples of a gel. The solid and liquid phases in a gel are interdispersed with both phases being continuous. In most systems, the major factor influencing the stability is the charge on the colloidal particles. If a particular ion is preferentially adsorbed on the surface of the particles, the particles in suspension will repel each other, thereby preventing the formation of aggregates that are larger than colloidal dimensions. The ion can be either positive or negative depending on the particular colloidal system, i.e., air bubbles accumulate negative ions, sulphur particles have a net negative charge in a sulphur sol, and the particles in a metal hydroxide sol are positively charged. Accumulation of charge on a surface is not an unusual phenomenon-dust is attracted to furniture surfaces by electrostatic forces. When salts are added to lyophobic colloidal systems the colloidal particles begin to form larger aggregates and a sediment forms as they settle. This phenomenon is called flocculation, and the suspension can be referred to as flocculated, or colloidally unstable. If the salt is removed, the suspension can usually be restored to its original state, this process is called deflocculation or peptization. The original and restored colloidal systems are called deflocculated, peptized, or stable sols. Why does a small amount of salt have such a dramatic effect on the stability of a lyophobic colloidal system? The answer lies in an understanding of the attractive and repulsive forces that exist between colloidal particles. Van der Waals forces are responsible for the attractions, while the repulsive forces are due to the surface charge on the particles. In a stable colloid, the repulsive forces are of greater magnitude than the attractive forces. The magnitude of the electrical repulsion is diminished by addition of ionized salt, which allows the dispersed particles to aggregate and flocculate. River deltas provide an example of this behaviour. A delta is formed at the mouth of a river because the colloidal clay particles are flocculated when the freshwater mixes with the salt water of the ocean (source: Sarquis, J. (1980). Colloidal systems. Journal of Chemical Education, 57(8), 602. doi:10.1021/ed057p602 ) Settling down of colloidal particles to form a suspension is called:

The French physicist Louis de Brogie in 1924 postulated that matter, like radiation, should exhibit a dual behaviour. He proposed the following relationship between the wavelength lambda of a material particle, its linear momentum p and planck constant h. lambda =(h)/(p) = (h)/(mv) The de Broglie relation implies that the wavelength of a particle should decrease as its velocity increase. its also implies that for a given velocity heavier particles should have shorter wavelength than lighter particles. The waves associated with particles in motion are called matter waves or de Broglie waves. These waves differe from the electromagnetic waves as they (i) have lower velocites (ii) have no electrcal and magnetic fields, and (iii) are not emitted by the particle under consideration. The experimental confirmation of the de Brgolie's relation was obtained when Davisson and Germer, in 1927, observed that a beam of electron is diffracted by a nickel crystal. As diffraction is a characterstic property of waves hence the beam of electron behaves as a wave, as proposed by de Broglie If proton, electron and alpha -particle are moving with same kinetic energy then the order of their de-Broglie's wavelength.
