what are colloids? Write their properties. Explain Tindal effect. Write different forms of colloids.
Answers
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:
I hope it's help you.
Explanation:
A colloid is a heterogeneous mixture whose particle size is intermediate between those of a solution and a suspension. The dispersed particles are spread evenly throughout the dispersion medium, which can be a solid, liquid, or gas. Because the dispersed particles of a colloid are not as large as those of a suspension, they do not settle out upon standing. The Table below summarizes the properties and distinctions between solutions, colloids, and suspensions.
