This compound is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called called "lunar caustic" because silver was called luna by the ancient alchemistsIn solid silver nitrate, the silver ions are three-coordinated in a trigonal planar arrangement.Albertus Magnus, in the 13th century, documented the ability of nitric acid to separate gold and silver by dissolving the silver. Magnus noted that the resulting solution of silver nitrate could blacken skin. Its common name is nitric acid silver. Chemical formula or symbol is AgNO3. The Density is 13.23g.cm-3.
