Chlorides

Nanoshel’s Silver Chloride is a chemical compound with the chemical formula AgCl. This white crystalline solid is well known for its low solubility in water. The chemical formula for Silver Chloride is AgCl. It is usually available as a white crystalline solid.. Silver chloride is virtually insoluble in water, but can be dissolved in aqueous solutions of ammonia, potassium cyanide and sodium thiocyanate. If placed in a sealed glass container (at atmospheric pressure) and exposed to sunlight (while shaking the container), Silver Chloride turns black. If then placed in a completely dark place, the Silver Chloride will eventually turn back to pure white.

The anomalous DC ionic conductivity of silver chloride at high temperatures. It is found that the conductivity anomaly in silver chloride along with the exponential increase of the dielectric constant at high temperatures may be explained by referring to the idea of a “soft lattice”, wherein silver ions are increasingly free to move about their regular lattice sites as the temperature rises. This wide ranging of silver ions leads to the formation of transient dipoles, which have the dual effect of increasing the dielectric constant and decreasing the free energy of the lattice.

Nanoshel’s Silver Chloride are used to make photographic film and photographic paper. Photographic paper coated in silver chloride is produced by bringing solutions of silver nitrate and potassium chloride solutions into contact on the paper in the absence of light. A photographic image of an object placed on it can be obtained when the paper is dried and exposed to strong light.

Many of the applications Nanoshel’s Silver Chloride are based on its light sensitive conversion to metallic silver, such as preparation of photographic films and photo chromic lenses. It is an important reference electrode used in cells, and is also used to prepare infrared windows, pottery glazes, and stained glass. AgCl has disinfectant/antiseptic properties and is used in antimicrobial products, wound healing products, personal deodorants, water treatment, and antidotes for mercury poisoning.

Nanoshel’s Silver Chloride chemical compound, AgCl, a white cubic crystalline solid. On exposure to light it becomes a deep grayish blue due to its decomposition into metallic silver and atomic chlorine. This light-sensitive behavior is the basis of photographic processes (see photography, still). Both the bromide and iodide are less soluble in water and more sensitive to light than the chloride. The bromide forms light yellow cubic crystals; the iodide forms yellow hexagonal or yellow-orange cubic crystals, depending on the temperature. Besides use in photography, silver chloride is used in silver plating, and silver iodide is used for seeding clouds. The chloride, bromide, and iodide occur naturally as the minerals cerargyrite, bromyrite, and iodyrite, respectively. Silver fluoride, AgF, forms colorless cubic crystals; it is much more soluble in water than the other silver halides.
