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 carbonate Silver carbonate Silver carbonate is the chemical compound with the formula AgCO. Silver carbonate is yellow but typical samples are grayish due to the presence of elemental silver. It is poorly soluble in water, like most transition metal carbonates. Silver carbonate can be prepared by combining aqueous solutions of sodium carbonate with a deficiency of silver nitrate. Freshly prepared silver carbonate is colourless, but the solid quickly turns yellow. Silver carbonate reacts with ammonia to give the explosive fulminating silver. With hydrofluoric acid, it gives silver fluoride. The thermal conversion of silver carbonate to silver metal proceeds via formation of
