A heterogeneous system where one component is scattered as incredibly small particles in another substance, known as the dispersion medium, is what is meant by the term "colloid," according to the correct definition.
- The gel is a type of colloid that consists of a solid dispersion medium and a liquid dispersed phase. Examples include cheese, butter, and jams. Foam, aerosol, emulsion, solid sol, and sol are some other colloid kinds.
- In a heterogeneous system known as a colloid, one component is dispersed (dispersed phase) as incredibly minute particles in a different substance called the dispersion medium.
- The definition of "lyophobic" is "hating liquids." Colloidal sols that are lyophobic must be made utilizing specific procedures as opposed to simply combining the ingredients with the dispersion medium. These are known as irreversible sols because, after precipitation, adding the dispersion medium does not bring the colloidal sol back to its original state.
- Related colloids begin to form above Kraft temperature. The associated colloids are also known as micelles. Creation of micelles only takes place above:
Critical Micelle Concentration (CMC)- Concentration of surfactants where the Formation of micelle takes place.
Kraft temperature (Tk)- Minimum temperature where the formation of micelle takes place.
Identify the INCORRECT statement regarding colloids? (A) Cheese is an example of Gel in which the dispersed phase is liquid, and the dispersion medium is solid. (B) A colloid is a homogeneous system in which one substance is dispersed (dispersed phase) as very fine particles in another substance called a dispersion medium. (C) The lyophobic colloids are also termed irreversible sols. (D) The formation of associated colloids takes place above Kraft temperature.
The assertion It is false to say that a colloid is a homogenous system in which one component is scattered (dispersed phase) as very small particles in another material called the dispersion medium.
