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).
- Emulsion, sol, aerosol and foam are the 4 types of colloids.
- Fog is an example of a colloid in which the dispersion phase is liquid, and the dispersion medium is gas.
- The size of colloidal particles ranges from 1 to 1000 nm.
- Lyophobic, Lyophilic and Association colloids are the three types of colloidal solutions.

The minute particles here are 1 to 1000 nanometers in diameter but they still remain suspended and do not settle at the bottom of the mixture. They are visible under an optical or an electron (smaller particles) microscope.
A colloid is a mixture in which one substance which has fine particles (dispersed phase) mixed into another substance (dispersion medium). The particles of the colloids have a range from 1 to 1000 nm in diameter. The solution is called colloidal dispersionbecause the particles of solutions do not mix or settle down. They are dispersed in the soluti...
Colloids can be classified according to different properties of the dispersed phase and medium. Firstly, based on the types of particles of the dispersed phase, colloids can be classified as: 1. Multimolecular colloids 2. Macromolecular colloids 3. Associated colloids
Based on the physical state of the dispersion medium and of the dispersed phase, colloids can be classified into: 1. Foam 2. Solid Foam 3. Aerosol 4. Emulsion 5. Gel 6. Solid Aerosol 7. Sols 8. Solid sols The following table describes the types along with examples: Based on the nature of the interaction between the dispersion medium and the dispers...
A colloid is a mixture in which one substance of microscopically dispersed insoluble particles are suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid. The colloid consists of a dispersed phase and a continuous phase.
What is Colloid? Colloids refer to dispersions of small particles usually with linear dimensions from around 1 nm to 10 micrometres.

A suspension is a mixture of particles with diameters of about 1 µm (1000 nm) that are distributed throughout a second phase. Common suspensions include paint, blood, and hot chocolate, which are solid particles in a liquid, and aerosol sprays, which are liquid particles in a gas.
Jun 19, 2020 · An emulsion is a colloidal dispersion of a liquid in either a liquid or a solid. A stable emulsion requires an emulsifying agent to be present. Mayonnaise is made in part of oil and vinegar. Since oil is nonpolar, and vinegar is a polar aqueous solution, the two do not mix and would quickly separate into layers.
