What is Silver Nitrate

Silver nitrate is an inorganic compound with chemical formula AgNO3.
This compound is a versatile precursor to many other silver compounds, such as those used in photography. Silver Nitrate is a salt. AgNO3 is widely used within laboratories, industrially and is also found in many common every day products. It is far less sensitive to light than the halides. When Silver Nitrate is added to water, the water cools. (endothermic) Applications for Silver Nitrate include testing for chloride, in the production of pharmaceuticals and as an antiseptic. 
Silver Nitrate is mainly used as the basic building block for making all Silver Compounds. It was once called lunar caustic because silver was called luna by the ancient alchemists, because they believed that silver was associated with the moon. It is extremely soluble in water. (2,570g / Liter @ 25°C). This is a dry, white powder. Always use Distilled Water (the grocery store type) when dissolving Silver Nitrate. Silver nitrate bonds with the eye membranes which results in redness, blurred vision, and swelling for several days.
Impure Silver Nitrate (the kind we don't sell) can be light sensitive. Solutions are manufactured by dissolving silver in Nitric Acid to a specified concentration. We also manufacture and supply Nitric Acid in a variety of grades. It is not light sensitive (even in direct sunlight) when kept inside a sealed container. Pure Silver Nitrate (the kind we sell) is not light sensitive. Never store or ship Silver Nitrate in Polyethylene bags or bottles! - it will get "gummy".
