Question

difference between colloidal and suspension write four point​

Answer 1

Explanation:

Particles in a suspension are usually more than 1,000 nm, while those in a colloid range from 1-1,000 nm. ... Colloids are able to scatter light, but suspensions cannot transmit light. Particles in a suspension can be seen by the naked eye, but those in a colloid must be viewed using a light microscope.

Answer 2

Explanation:

A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution, so gravity is able to pull them down out of the dispersion medium (water). The diameter for the dispersed particles in a suspension, such as the sand in the suspension , is typically at least 1000 times greater than those in a solution. Unlike a solution, the dispersed particles can be separated from the dispersion medium by filtering. Suspensions are still considered heterogeneous because the different substances in the mixture will not remain uniformly dispersed if they are not actively being mixed.

WHEREAS,

A colloid is a heterogeneous mixture in which the dispersed particles are intermediate in size between those of a solution and a suspension. The 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.
