Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is Colloid is a homogeneous mixture.
Key Points
- Colloids are mixtures where one substance of microscopically dispersed insoluble particles is suspended throughout another substance.
- Colloids cannot be separated by filtration due to the small size of the dispersed particles.
- Colloids are heterogeneous mixtures because the composition is not uniform throughout.
- Particles in a colloid do not settle down when left undisturbed because of their small size and constant motion caused by Brownian motion.
Additional Information
- Brownian Motion:
- The random movement of particles suspended in a fluid (liquid or gas) resulting from their collision with fast atoms or molecules in the gas or liquid.
- Tyndall Effect:
- The scattering of light by particles in a colloid or in a very fine suspension.
- Types of Colloids:
- Based on the state of the dispersed phase and the dispersion medium, colloids can be classified into various types like sols, gels, foams, and emulsions.
- Examples of Colloids:
- Milk (emulsion), fog (aerosol), and jelly (gel).
