As we’ve outlined in recent blogs, homogenization is a process utilized for fragment size reduction and also works by employing mechanical force to breakdown particles or droplets in a liquid right into smaller and an ext uniform sizes. The an outcome of homogenization is a dispersion, wherein fine particles of one substance are scattered throughout an additional substance. Furthermore, dispersions room able to it is in classified by the sizes of this scattered particles: solutions, suspensions and colloids. In this blog, we’re concentrating on the difference between suspension and also colloids.

You are watching: How does a suspension differ from a solution?


Simply characterized as a heterogeneous mixture of two substances in which one is distributed into the other, suspensions show off particles bigger than those discovered in solutions, frequently over 1,000 nm. The bigger corpuscle of a suspension usually resolve or separate out that a mixture ~ above standing or are able to it is in filtered out, return not through filter paper. Heaviness is may be to traction the clearly shows particles in a suspension down if undisturbed, and also they will continue to be that way unless being actively mixed. Examples of suspensions incorporate oil and water, dust or soot in air, sand and also water and also muddy water.


Although a heterogeneous mixture of two substances like suspensions, colloids involve particles from 1-1,000 nm that perform not different upon standing and also cannot be separated through filtration. The corpuscle in a colloid soil in size in between those in a solution and a suspension and may it is in solid, fluid or gas. The two parts in every colloid mixture are its particles and also the dispersing medium, and the particles space spread same in in the medium, i m sorry can also be solid, liquid or gas. Instances of colloids room foams (shaving cream, Styrofoam), gels (gelatin, jelly), emulsions (mayonnaise, lotion), aerosols (fog, insecticide spray, smoke) and sols (shampoo, gemstones).

Even though the corpuscle in a colloid space very little in size, they have the right to be seen through a procedure called the Tyndall Effect, the effect of light scattering in colloidal dispersion while reflecting no irradiate in a true solution. This result is provided to recognize whether a mixture is a true solution or a colloid.

Colloid mills, prefer homogenizers,are able to process particle palliation formulations, although each is preferential for specific applications.They are ideal used because that samples made up of solids immersed in a liquid suspension or a liquid suspended in an additional liquid since they have the right to enhance the security and/or alleviate the dimension of suspended particles.

In summary, adhering to are some of the main differences between a suspension and also colloid:

Particles in a suspension room usually an ext than 1,000 nm, if those in a colloid selection from 1-1,000 nm.Unlike those in a suspension, corpuscle in a colloid perform not separate once sitting still. The corpuscle in a suspension might be be separated by filtration unequal those in a colloid.Colloids room able to scatter light, yet suspensions cannot transmit light.Particles in a suspension can be seen by the naked eye, yet those in a colloid should be viewed using a irradiate microscope.
