Silver chromate is an inorganic compound with formula Ag2CrO4 which appears as distinctively coloured brown-red crystals. The compound is insoluble and its precipitation is indicative of the reaction between soluble chromate and silver precursor salts (commonly potassium/sodium chromate with silver nitrate). This reaction is important for two uses in the laboratory: in analytical chemistry it constitutes the basis for the Mohr method of argentometry, whereas in neuroscience it is used in the Golgi method of staining neurons for microscopy.

  • Silver chromate is an inorganic compound with formula Ag2CrO4 which appears as distinctively coloured brown-red crystals. The compound is insoluble and its precipitation is indicative of the reaction between soluble chromate and silver precursor salts (commonly potassium/sodium chromate with silver nitrate). This reaction is important for two uses in the laboratory: in analytical chemistry it constitutes the basis for the Mohr method of argentometry, whereas in neuroscience it is used in the Golgi method of staining neurons for microscopy. In addition to the above, the compound has been tested as a photocatalyst for wastewater treatment. The most important practical and commercial application for silver chromate, however, is its use in Li-Ag2CrO4 batteries, a type of lithium battery mainly found in artificial pacemaker devices. As for all chromates, which are chromium(VI) species, the compound poses a hazard of toxicity, carcinogenicity and genotoxicity, as well as great environmental harm. (en)

  • Il cromato d'argento è un sale inorganico di formula Ag2CrO4. In condizioni standard appare come un solido cristallino di colore bruno, inodore, insolubile in acqua ma ben solubile in acido nitrico ed ammoniaca. Trova impiego come reagente nelle sintesi chimiche. (it)

  • O Cromato de Prata (Ag2CrO4) é um sal monocíclico vermelho-amarronzado e é um precursor químico da fotografia moderna. Ele pode ser formado combinando Nitrato de Prata (AgNO3)e cromato de potássio (K2CrO4) ou cromato de sódio(Na2CrO4). Esta reação é importante na neurociência, por ser usada no Método de Golgi de coloração de neurônios para microscopia: o cromato de prata produzido precipita dentro dos neurônios e faz sua morfologia visível.
