FAQs on Properties of Colloid Video Lecture - CSIR NET Crash Course for Chemical Science - CSIR NET Chemical Science
| 1. What are the properties of colloids? |  |
Ans. Colloids exhibit the following properties:
- They are heterogeneous mixtures.
- They do not settle down on standing.
- They scatter light, known as the Tyndall effect.
- They have large surface area to volume ratio.
- They show Brownian motion.
| 2. How are colloids classified based on the dispersed phase and dispersion medium? | |
Ans. Colloids are classified as:
- Sol: dispersion medium is solid and dispersed phase is liquid.
- Gel: dispersion medium is liquid and dispersed phase is solid.
- Foam: dispersion medium is gas and dispersed phase is liquid.
- Emulsion: dispersion medium is liquid and dispersed phase is liquid.
- Aerosol: dispersion medium is gas and dispersed phase is solid.
| 3. What is the significance of colloids in various industries? | |
Ans. Colloids play a vital role in various industries. They are used in cosmetics, pharmaceuticals, food industry, paints, and coatings. Colloids help in stabilizing emulsions, suspensions, and foams, thereby improving the texture, appearance, and shelf life of products.
| 4. How do we prepare colloids in the laboratory? | |
Ans. Colloids can be prepared in the laboratory by methods such as:
- Condensation method: where small particles are formed by condensation of gases.
- Dispersion method: where large particles are broken down into smaller ones by mechanical means.
- Chemical method: where chemical reactions lead to the formation of colloidal particles.
| 5. How do colloids differ from solutions and suspensions? | |
Ans. Colloids differ from solutions and suspensions in terms of particle size. Colloids have particles larger than those in solutions but smaller than those in suspensions. Unlike solutions, colloids do not settle down on standing. They also scatter light, unlike suspensions.
