Colloid is a term that has come to encompass solid particles suspended in a liquid (a colloidal dispersion), microscopic droplets in a liquid (an emulsion), or either solid or liquid phases suspended in a gas (an aerosol).
27 Σεπ 2022 · A colloid is a mixture consisting of microscopic particles suspended in another medium. Examples include milk, smoke, gelatin, ink, and hand lotion. In chemistry, a colloid is a mixture of tiny particles that are dispersed in another medium.
Examples. Continuous phase is often water. Wide range of sizes: bovine serum albumin: 3 nm. cells: tens of microns. Classify colloids as hydrophobic (e.g., carbon black) or hydrophilic (e.g., red blood cell). Stability of colloid: essential part of its function. whether or not it will coagulate.
11 Σεπ 2022 · A colloid is also a heterogeneous mixture, but the particles of a colloid are typically smaller than those of a suspension, generally in the range of 2 to about 500 nm in diameter. Colloids include fog and clouds (liquid particles in a gas), milk (solid particles in a liquid), and butter (solid particles in a solid).
Describe the composition and properties of colloidal dispersions. List and explain several technological applications of colloids. As a child, you may have made suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water, known as tempera paint.
30 Ιαν 2023 · A colloid is a mixture that has particles ranging between 1 and 1000 nanometers in diameter, yet are still able to remain evenly distributed throughout the solution. These are also known as colloidal dispersions because the substances remain dispersed and do not settle to the bottom of the container.
