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 …

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.

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

Jan 1, 2026 · A colloid is a heterogeneous mixture at a microscopic level whose particle size is intermediate between a solution and a suspension. Tyndall effect is the scattering of visible light by …

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 …

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.
