Silver perchlorate Silver perchlorate Silver perchlorate is the chemical compound with the formula AgClO. This white solid forms a monohydrate and is mildly deliquescent. It is a useful source of the Ag ion, although the presence of perchlorate presents risks. It is used as a catalyst in organic chemistry. Silver perchlorate is created by heating a mixture of perchloric acid with silver nitrate. Alternatively, it can be prepared by the reaction between barium perchlorate and silver sulfate, or from the reaction of perchloric acid with silver oxide. Silver perchlorate is noteworthy for its solubility in aromatic solvents such as benzene (52.8 g/L)
Silver chromate Silver chromate Silver chromate (AgCrO) is a brown-red monoclinic crystal and is a chemical precursor to modern photography. It can be formed by combining silver nitrate (AgNO) and potassium chromate (KCrO) or sodium chromate (NaCrO). This reaction has been important in neuroscience, as it is used in the "Golgi method" of staining neurons for microscopy: the silver chromate produced precipitates inside neurons and makes their morphology visible. Silver chromate is produced by an exchange reaction with a soluble silver salt, such as that between potassium chromate and silver nitrate. The use of the compound itself in the laboratory is rather
