What is a colloid?
colloid is the final result of dispersing one substance evenly and microscopically in another without any changes in the structure of both. Colloids differ from other combinations, such as the solution, because none of the Union components will dissolve or experience any structural changes during the scattering. Colloids may exist in combinations of all states of matter, including gaseous, liquid and solid trade unions. In an emulsified state, colloidal trade unions can consist of one or more of the uncommon components, where surface active substances maintain a uniform distribution of individual parts. Some well -known examples of colloids are milk and fog.
Mixtures or departments of different materials and substances exist in different forms. In most, one or more individual parts of the mixture undergo some physical or chemical change. Unlike combinations, such as solvents and alloys, colloidal mixtures have a uniform distribution of all ingredients in their original, unjustified form. This means that colloids add individualThose of all their parts and not a reactive combination of properties. In this way, the active ingredients can be suspended in inert support media without change or negatively affecting their properties.
colloid mixtures consist of two different parts: scattered phases or substances and dispersion media. As an example, a colloid consisting of a dispersion phase of a liquid butterfly distributed to a dispersion medium based on water. Colloids may consist of a combination of all states of matter with conventional trade unions, including fluid/air mixtures such as fog and fog and solid/air trade unions such as smoke or cloud mass. Other common combinations include a liquid/gas mixture, such as whipped cream, a combination of liquid/solid gel such as gelatin, and dispersion in a solid/liquid that includes blood and inks. Decorative cranberries need a solid/solid colloid and is a combination of red glass and gold chloride.
The individual parts of the liquid/liquid colloids are not always miscible or mixable and after the combination they would gradually separate if no other ingredients were introduced. These additives are known as superficially active substances and changes the characteristics of the surface tension of the mixture that support immobile components to remain evenly distracted. Milk is one of the most famous examples of these trade unions or emulsions. Colloids can also be formulated to show unstable, fractional properties that allow them to flow when stress is exposed, and then regain cohesion as soon as the stress is terminated. One example of this phenomenon is a toothpaste that flows when the tube is pressed and then remains stable on the toothbrush.
