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 heterogeneous mixtures in which particles do not degrade the substance by remaining in the solution.
Colloidal particles can be dispersed in solids, liquids and gases. One substance, made of very fine particles, is dispersed among another medium. The particles that scatter into the medium can be solids, liquids and gases.
Colloids in which the solid is the medium include gemstones, pearls, cheese, butter, jelly, jam, pumice and foam rubber. Gems are examples of a solid dispersed into another solid. Cheese features liquid particles dispersed among a solid medium, while foam rubber is a gas filtered through a solid.
Liquid media that disperse solid particles include paint and gum. Liquids that disperse other liquids are milk, hair cream and cod liver oil. Gas particles across a liquid are whipped cream and soap lather.
Smoke, dust, clouds, fog and insecticide sprays are examples of a gas dispersal medium in colloidal substances. Colloids dispersed in gases are also known as aerosol sprays. Colloids made of gases and other gases are impossible to make in chemistry because the two gases combine evenly to form a completely homogeneous mixture, according to XAmplified, a free online education resource.Learn More
Water, an inorganic compound, is important because it makes up as much as 70 percent of the body weight of an adult body, according to a Rice University article published on the Openstax College website. The other groups of inorganic compounds that are essential to the body include salts, acids and bases.Full Answer >
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.Full Answer >
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 water. Specifically, it is a type of colloid known as a sol, a colloid of solid particles dispersed through another substance. The lesser ingredient in a colloid, in this case gelatin, is called the dispersed phase.Full Answer >
The Kp in the study of chemistry is an equilibrium constant of both heterogeous and homogeneous gaseous reactions, according to ChemGuide. Value is determined by the partial pressures of the gases inside a closed system.Full Answer >
