Differbetween
A colloidal solution is a mixture in which one substance is dispersed in another medium. It contains both dispersed phase and dispersed medium. Whereas micelle is an aggregate or surfactant molecule dispersed in a liquid colloid. Thus it is a dispersed phase and not the whole colloidal solution.

How do micelles differ from ordinary colloidal particles?
How do they differ from ordinary colloidal particles ? Give two examples of micelles forming substances. ... This is known as micelle formation and the cluster that is formed is called as micelle. micelle system behaves as a true solution in low concentration and as colloidal solution as high concentration.
Is a micelle a colloid?
Micelles are nanosized colloidal dispersions prepared from amphiphilic molecules, with a hydrophobic tail and a hydrophilic head. ... Polymeric micelles are prepared by increasing the concentration of the molecules above the corresponding critical micelle concentration.
What are micelles how do they differ from ordinary colloidal particles give two examples of micelle forming substances?
The aggregated particles thus formed are called micelles. The formation of micelles takes place only above a particular temperature called Kraft temperature and above a particular concentration (CMC). On dilution these colloids revert back to individual inos. Examples are soaps and sytheric detergents.
What is the difference between colloid and colloidal solution?
Colloids (also known as colloidal solutions or colloidal systems) are mixtures in which microscopically dispersed insoluble particles of one substance are suspended in another substance. The size of the suspended particles in a colloid can range from 1 to 1000 nanometres (10-9 metres).
What is the meaning of micelles?
A micelle (/maɪˈsɛl/) or micella (/maɪˈsɛlə/) (plural micelles or micellae, respectively) is an aggregate (or supramolecular assembly) of surfactant molecules dispersed in a liquid, forming a colloidal suspension (also known as associated colloidal system). ... Micelles are approximately spherical in shape.
What are micelles give one example?
Micelles are associated colloids which arrange in radial manner. ... Micelles may contain as many as 100 molecules or more. For example, soap on dissolving in water, gives sodium and stearate ions. The stearate ions associate to form ionic micelles of colloidal size.
How is micelle formed?
Micelles are formed by self-assembly of amphiphilic molecules. ... Micelles are formed in aqueous solution whereby the polar region faces the outside surface of the micelle and the nonpolar region forms the core. Micelles can deliver both hydrophilic and hydrophobic agents.
Why are micelles spherical?
The hydrophobic tails are inside and away from the water since they are nonpolar. Fatty acids from micelles usually have a single hydrocarbon chain as opposed to two hydrocarbon tails. This allows them to conform into a spherical shape for lesser steric hindrance within a fatty acid.
How does soap become a micelle?
When greasy dirt, fat, or oil is mixed with soapy water, the soap molecules arrange themselves into tiny clusters called micelles. ... The water-loving (hydrophilic) head of the soap molecules sticks to the water and points outwards, forming the outer surface of the micelle.
What are micelles in chemistry?
Micelle, in physical chemistry, a loosely bound aggregation of several tens or hundreds of atoms, ions (electrically charged atoms), or molecules, forming a colloidal particle—i.e., one of a number of ultramicroscopic particles dispersed through some continuous medium.
What are micelles discuss the mechanism of micelle formation and cleaning action of soap?
The dirt present on clothes is organic in nature and insoluble in water. ... Then, the molecules of soap arrange themselves in micelle formation and trap the dirt at the centre of the cluster. These micelles remain suspended in the water. Hence, the dust particles are easily rinsed away by water.
