How is colloid distinguished from a solution or a suspension?

Answer 1

Solution: one phase system (solute or solutes in a solution)

Colloid: two phases system, very stable dispersion in a dispersion medium, particles in the range 5-200 nm

Suspension: two phases (or more) system, unstable, particles above 200 nm

A colloid is distinguished from a solution and a suspension by the particles, because they usually have an electric charge, and they repel each other, so they do not collect into larger perticles that would settle out like those in solutions, and suspensions.

Answer 2

Colloid have comparatively smaller particles and it is stable(particles do not settle down when left undisturbed). Whereas, suspensions have comparatively larger particles and they settle down after sometime when left undisturbed.

Answer 3

Colloids are homogeneous mixtures where particles are evenly distributed but not dissolved, leading to a stable dispersion. Solutions are homogeneous mixtures where solute particles are dissolved uniformly in the solvent. Suspensions are heterogeneous mixtures where particles are not dissolved and settle out over time.

Answer 4

the colloidal particle show tyndal effect while suspended particles donot. Colloidal particles donot settle down but the suspended particles get settledown.

Answer 5

- The dimension of colloids is lower
- Suspensions have the trend to sedimentation
