Silver oxide Silver oxide Silver(I) oxide is the chemical compound with the formula AgO. It is a fine black or dark brown powder that is used to prepare other silver compounds. Silver oxide can be prepared by combining aqueous solutions of silver nitrate and an alkali hydroxide. This reaction does not afford appreciable amounts of silver hydroxide due to the favorable energetics for the following reaction: US patent 20050050990 describes the preparation of AgO with properties suitable for use as a fine grained conductive paste filler. AgO features linear, two-coordinate Ag centers linked by tetrahedral oxides. It is isostructural with CuO. It
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
