Answer 1

Explanation:

• a homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle, and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.

• The types of colloids includes sol, emulsion, foam, and aerosol.
• Sol is a colloidal suspension with solid particles in a liquid.
• Emulsion is between two liquids.
• Foam is formed when many gas particles are trapped in a liquid or solid.
• Aerosol contains small particles of liquid or solid dispersed in a gas.
• A common method of classifying colloids is based on the phase of the dispersed substance and what phase it is dispersed in. The types of colloids includes sol, emulsion, foam, and aerosol. Sol is a colloidal suspension with solid particles in a liquid. Emulsion is between two liquids.

Answer 2

Answer:

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:

Multimolecular colloids

Macromolecular colloids

Associated colloids

Foam

Solid Foam

Aerosol

Emulsion

Gel

Solid Aerosol

Sols

Solid sols
