FAQs on Classification of Colloids: Lyophobic & Lyophilic Video Lecture - Chemistry Class 12 - NEET
| 1. What is the difference between lyophobic and lyophilic colloids? |  |
Ans. Lyophobic colloids are colloidal particles that are not attracted to the dispersion medium, while lyophilic colloids are colloidal particles that have a strong affinity for the dispersion medium. Lyophobic colloids require the addition of a stabilizing agent to prevent them from coagulating, while lyophilic colloids are stable without the need for any additional agent.
| 2. How do lyophobic colloids form? | |
Ans. Lyophobic colloids form when the dispersed phase particles have a weak affinity for the dispersion medium. They can be formed by methods such as condensation, dispersion, or chemical reactions. These colloids are typically unstable and tend to coagulate or precipitate.
| 3. What are some examples of lyophilic colloids? | |
Ans. Lyophilic colloids include substances such as gelatin, starch, proteins, and natural rubber. These substances have a high affinity for the dispersion medium and can form stable colloidal solutions without the need for any additional stabilizing agent.
| 4. How are lyophobic colloids stabilized? | |
Ans. Lyophobic colloids are stabilized by the addition of a stabilizing agent, also known as a protective colloid. These agents adsorb onto the surface of the colloidal particles, creating a repulsive force between them and preventing coagulation or precipitation. Examples of stabilizing agents include gum arabic, sodium dodecyl sulfate, and polyvinyl alcohol.
| 5. What are the applications of colloids in everyday life? | |
Ans. Colloids have numerous applications in everyday life. They are used in various industries such as food, pharmaceuticals, cosmetics, and paints. Some examples include the use of colloidal suspensions in food products to improve texture and stability, the use of colloidal systems in drug delivery systems, and the use of colloidal nanoparticles in sunscreen to provide better UV protection.
