Silver halide Silver halide A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver and one of the halogens. In particular, bromine, chlorine, iodine and fluorine may each combine with silver to produce silver bromide (AgBr), silver chloride (AgCl), silver iodide (AgI), and three forms of silver fluoride, respectively. As a group, they are often referred to as the silver halides, and are often given the pseudo-chemical notation AgX. Although most silver halides involve silver atoms with oxidation states of +1 (Ag), silver halides in which the silver atoms have oxidation states of
Silver chloride Silver chloride Silver chloride is a chemical compound with the chemical formula AgCl. This white crystalline solid is well known for its low solubility in water (this behavior being reminiscent of the chlorides of Tl and Pb). Upon illumination or heating, silver chloride converts to silver (and chlorine), which is signaled by greyish or purplish coloration to some samples. AgCl occurs naturally as a mineral chlorargyrite. Silver chloride is easily synthesized by combining aqueous solutions of silver nitrate and sodium chloride. It can also be produced by reacting silver nitrate with cobalt(II) chloride. The solid adopts the "fcc" NaCl structure,
