Definition of aerosol, foam, Sol, gel, solid Sol, and emulsion in chemistry
Answers
Answer:
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.

Answer:
Aerosol: When particles of solid or liquid get dispersed in a gaseous medium, the mixture is known as Aerosol. For example – cloud, fog, smoke etc.
• Foam: Foam is a colloidal system where the dispersed phase is gas, and the dispersion medium is solid or liquid. (Solid dispersion medium for solid foam only.)
• Emulsion: Emulsion is a colloidal system where the dispersed phase is liquid, and the dispersion medium is another liquid.
• Sol: Sol is a colloidal system where the dispersed phase is solid, and the dispersion medium is liquid.
• Gel: Gel is a colloidal system where the dispersed phase is solid, and the dispersion medium is liquid.
• Solid sol: Solid sol is a colloidal system where the dispersed phase is solid, and the dispersion medium is another continuous solid.
