Can solution particles be seen
WebColloids. 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 … WebJan 11, 2024 · Particles in a colloidal solution can always be seen by naked eyes. Scattering of light occurs when a beam of liquid is passed through aqueous sugar solution. Colloidal solutions are of heterogeneous nature. Digestion of food is a chemical change.
