The main difference between a colloid and a suspension is that a suspension will separate into particles, but a colloid will not. A colloid is the middle line between a suspension and a solution. More »

Heterogeneous mixtures that never settle are called colloids. Colloidal dispersions, as they are known in chemistry, remain evenly distributed without settling out. Examples include butter, milk, smoke, fog, ink and pain... More »

A mixture of water and starch is colloidal because it forms a shell of firmly bound molecules of water that stops the starch particles from aggregating with the molecules of water when they collide. However, when heated,... More »

Gelatin, when dissolved in water, is a colloid because the protein molecules that compose it, mostly derived from collagen, are much larger than usual dissolved molecules, but they remain evenly dispersed throughout the ... More »

Colloid chemistry is vitally important to many industrial processes such as the manufacture of paint, paper, ceramics, adhesives, pharmaceuticals, foods and composites, according to Columbia University. Colloids are hete... More »

Blood has the characteristics of both a colloid and a suspension and is therefore a colloidal suspension. Since blood has characteristics of all three mediums, its true nature is hard to ascertain. More »

The particles in a colloid are larger than those found in a solution. The sizes of the particles in a colloid range from 10^-8 to 10^-6 meters, while a solution is made up of ions, atoms or molecules, which are 10^-9 met... More »
