1 iul. 2012 This is an example of a gas-liquid colloid where gas is trapped within a liquid to form a stable mixture. 2. Liquid-liquid colloid (an ...

Colloids contain some particles that are intermediate between those in a solution and those in a suspension. Examples include peanut butter pudding

Colloids are materials that display phase structures larger than those that display quantum effects (atomic and molecular) but small enough that the structures are sensitive to thermal fluctuations (smaller than 50 µm or the thickness of a hair) that is colloids are affected by Brownian motion and are subject to diffusion

Network colloid : consists of two inter-penetrating networks and hard to specify which is dispersed and which is continuous phase (porous glass opal glass gels) Practical examples of colloidal system 10 2 2 Colloid Size The size of dispersed phase falls in the range of 1~1000nm

A colloid is a solution in which the particle size ranges between 10-7cm and 10-5cm For example milk blood honey smoke ink gum starch solution etc Every colloid consists of two parts: colloidal particles or (Dispersed Phase) and the dispersing medium The dispersing medium is the substance in which the colloidal particles are

For example colloidal solutions ofstarch gelatin gum etc are prepared by simply dissolving these substances inhot water Similarly a colloidal sol of cellulose nitrate is obtained by dissolving itin alcohol The resulting solution is called collodion However lyophobic colloids cannot be prepared by direct method

Common examples of colloids: The colloidal particles are not necessarily corpuscular in shape In fact these may be rod-like disc-like thin films or long filaments For matter in the form of corpuscles the diameter gives a measure of the particle size
