Silver nitrate
Silver Nitrate
Silver nitrate (pronunciation: /ˈsɪlvər ˈnaɪ.treɪt/) is an inorganic compound with the chemical formula AgNO3. 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.
Etymology
The term "silver" derives from the Old English seolfor, which itself comes from the Proto-Germanic *silubra. The chemical symbol for silver, Ag, comes from the Latin word for silver, argentum. "Nitrate" comes from the Latin nitrum, meaning "native soda", and the suffix "-ate", used in chemistry to denote a compound containing a specified element or group.
Usage
Silver nitrate is used in many ways. In medicine, it is used as a cauterizing agent, for removing warts and granulation tissue. It is also used in dyeing and tanning processes, and in photography for its light-sensitive characteristics.
