Brownian Movement: It is also known as Brownian motion, after the scientist who discovered it in 1827, named Robert Brown (a botanist). It is defined as a continuous random movement of microscopic particles dispersed in liquid or gas, particularly in a zig-zag manner.

At this small scale, it is believed that large particles are continuous with each other and the rest on the medium. eastpak floid canvas backpackWebThe properties of colloidal dispersions are closely linked to the high surface area of the dispersed phase and the chemistry of these interfaces. This natural combination of colloid and surface chemistry represents a major research space and we get to see a variety of categories of colloids based on these basic properties. eastpak leatherfaceWebA group of mixtures called colloids (or colloidal dispersions) exhibit properties intermediate between those of suspensions and solutions (Figure 1).
