which are the properties of colloidal solution ?

Text Solution

Verified by Experts

The important properties of colloidal sol are as follows:
i) Heterogeneous nature: Colloidal sols are heterogeneous in nature. They exhibit two different phases that is dispersed phase and dispersion medium. ii) Optical properties :Colloidal solutions exhibit Tyndall effect which shows the optical nature of sols. iii) Mechanical property : Colloidal solutions exhibit continuous zig-zag motion which determines the mechanical property of sols. This is known as Brownian movement. iv) Charge on colloidal particles : Colloidal particles bear some charges, either it may be positive or negative. v) Colour of colloids : The colour of colloidal solution depends on the wavelength of light scattered by the dispersed particles.

A colloidal solution is a type of mixture which consists of particles whose size varies between 1 and 1000 nanometres. In colloidal solution the particles are distributed evenly. During this process the particles do not settle down. This is one of the best know thing about colloidal solutions. Properties of colloids and their variation are a well-known area ever since the primitive age. The best example to prove their familiarity with us is that we know from very early times that coagulation of milk results in the formation of curd. Physical properties of colloids 1. The nature of the colloidal solution is heterogeneous i.e. unlike. These solutions dwell with two different phases : • Dispersed medium Dispersed phase. 2. Despite the fact that colloidal dispersions are unlike in description (nature), yet the dispersed fragments are not detectabJe by the human eye. This is due to the microscopic size of the particles in the solution. 3. The colour of the colloidal dispersion is determined by particles in the solution based on their size. The wavelengths of light that is absorbed will be longer ifthe size of the particle is large. 4. As a result of its size, the colloidal fragments can easily be passed through a traditional filter paper. However, these particles can be filtered by using membranes such as animal, cellophane, and ultrafilters. What type of phases of colloidal solutions ?
