A colloid is a mixture in which one substance, consisting of microscopically dispersed insoluble particles, is suspended throughout another substance. Some definitions specify that the particles must be …

Sep 27, 2022 · In chemistry, a colloid is a mixture of tiny particles that are dispersed in another medium. The particles are microscopic in size, ranging from 1 nanometer (nm) to 1 micrometer (μm) in diameter.

Dec 29, 2025 · Colloid, any substance consisting of particles substantially larger than atoms or ordinary molecules but too small to be visible to the unaided eye. Colloidal systems may exist as dispersions …

A colloid, or a colloidal solution, is a mixture consisting of molecules or particles dispersed in solution. Unlike the other two primary types of mixture, solutions and suspensions, colloids contain particles …

What are colloids. Learn its properties, types, and applications. Check out a few examples of colloid fluids.

The particles of a colloid remain dispersed and do not settle due to gravity, and they are often electrically charged. Colloids are widespread in nature and are involved in many technological applications.

: a mixture (as smoke) consisting of a colloid together with the medium in which it is dispersed

The term “colloid”—from the Greek words kolla, meaning “glue,” and eidos, meaning “like”—was first used in 1861 by Thomas Graham to classify mixtures such as starch in water and gelatin.

A colloid is a heterogeneous mixture whose particle size is intermediate between those of a solution and a suspension. The dispersed particles are spread evenly throughout the dispersion medium, which …

Air, water, and plastics are common examples. The colloid particles make up the dispersed or suspended phase when uniformly distributed in the second, continuous phase. The dispersed matter …
