kolloidní

Kolloidní refers to a state of matter where one substance is dispersed evenly throughout another. This dispersion involves particles that are larger than molecules but too small to be seen with the naked eye or under a standard microscope. These colloidal particles are suspended and do not settle out over time, unlike in a true suspension. Examples of colloids include milk, fog, and paint. The dispersed substance is called the dispersed phase, and the substance in which it is dispersed is called the dispersion medium. Colloidal systems exhibit unique properties, such as the Tyndall effect, where light beams passing through them become visible due to scattering by the colloidal particles. They also have a large surface area to volume ratio, which influences their chemical reactivity. The study of colloids is known as colloid chemistry.
