Silver chromate (Ag2CrO4) is a brown-red monoclinic crystal and is a chemical precursor to modern photography. It can be formed by combining silver nitrate (AgNO3) and potassium chromate (K2CrO4) or sodium chromate (Na2CrO4). 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.
