Properties of Colloids
There are many physical and chemical properties colloids have, some of those properties are as follows:
- As the size of particles is very small (1-1000 nanometers), they can’t be filtered using the basic filtration method. To filter colloids, we need more specialized filtration methods, such as ultrafiltration or centrifuge.
- Colloids are very stable. and when left untouched for long periods it doesn’t show the sign of sedimentation or precipitation.
- Colloids are heterogeneous mixtures, where the dispersed medium is suspended in the dispersion phase in nor uniform arrangement.
- Despite the heterogeneous nature of colloids, they seem to have a homogenous appearance. This is because the particle is very small in colloids which can’t be seen by the naked eye.
Colloids
Colloids or Colloidal Solution is a type of mixture in which insoluble components are suspended on a microscopic scale in some another component. Colloids are essential components in the daily lives of the common man, as we use or consume colloids and we even don’t know. From Jellys to Mayonese to the majority of beauty products, are some forms of colloids. Thus, understanding colloids will help us understand these things we use on a daily basis but don’t know about. In this article, we will learn about colloids in detail including their classification, properties, preparation method, and applications.
