DIFFUSION COLLOID Meaning and
Definition
-
Diffusion colloids, also known as sols, are a type of colloid where particles are dispersed in a continuous medium through diffusion. A colloid is a mixture consisting of tiny particles or droplets that are suspended within a substance. Diffusion colloid is characterized by the size of the dispersed particles, which are typically larger than molecules but smaller than those found in suspensions.
In a diffusion colloid, the dispersed particles can vary in composition, shape, and size, but they are usually solid. They remain dispersed throughout the continuous medium due to the random Brownian motion of the particles, which causes them to move and spread evenly within the solution. This diffusion process prevents the particles from settling at the bottom or rising to the top of the medium.
Diffusion colloids exhibit unique properties and behavior due to their particle size. They are typically stable and do not separate over time, maintaining a uniform consistency. However, they can still scatter light due to the interaction between light waves and the dispersed particles, giving rise to a visible effect known as the Tyndall effect.
These colloid systems are widely used in various fields, including medicine, industry, and research. They find applications in drug delivery systems, protective coatings, paints, and numerous other products. Moreover, diffusion colloids have played a significant role in scientific investigations, as they allow for the study of particle behavior and interactions in a controlled environment.

Etymology of DIFFUSION COLLOID
The word "diffusion" comes from the Latin word "diffusio", which is derived from the verb "diffundere". "Diffundere" is a compound of the prefix "dis-" meaning "apart or away", and "fundere" meaning "pour". Thus, "diffusion" refers to the act of spreading or scattering apart.
The term "colloid" comes from the Greek word "kolla", which means "glue". It was first used in this context by the Scottish chemist Thomas Graham in the mid-19th century. "Colloid" refers to a substance made up of tiny particles dispersed in another substance, forming a stable mixture.
