Nitric Acid Silver is the ancient name given to Silver Nitrate, an inorganic compound with a wide range of uses. Nitric Acid Silver was first discovered in the Middle Ages by a scientist and chemist known as Albertus Magnus. A scholar of theology, astronomy, astrology, botany, geography and philosophy, it was Albertus Magnus who first experimented with light-sensitive materials such as Nitric Acid Silver.
AgNO3 is the chemical formula for Silver Nitrate, a silver salt which is often supplied in a wide range of molarities. One of the most widespread uses of Silver Nitrate is the test for Chlorides by titration method. Thus is often performed by marine engineering companies to check for seawater contamination in dock areas and shipping.
Nitric Acid Silver is also used for mirroring glass and for wound dressings and salves because of its ability to sterilize wounds. Silver Nitrate is also used to coat catheters in order to minimise the risk of infection. It is essential that any solution of Silver Nitrate is made with high purity water, either Deionized Water or Distilled Water. The slightest trace of Chlorine in the water will cause the whole solution to turn black.
As Silver Nitrate is highly light-sensitive, it is also widely used in photography and Silver Nitrate is often sold as ‘photographic grade’. Typically, photographic grades of AgNO3 are of high quality and conform to analytical grade standard. General technical grade or laboratory grade Silver Nitrate is not generally available either in solid form or in solution.
A solution of Nitric Acid Silver must be stored away from the light as it is extremely light sensitive. It is usually stored in opaque containers of glass or plastic. When transporting Silver Nitrate, it is essential that it is packed in UN packaging in accordance with the ADR Regulations and that the containers are light-resistant. Even fairly small volumes of Silver Nitrate are classified as hazardous.
The price of Silver Nitrate is closely linked to the price of silver bullion which means that it is subject to great variation and can change even on a daily basis. It is also quite expensive which makes it prohibitive for some applications which can work equally well with less expensive materials.
One of the most significant points about working with or handling Silver Nitrate is that it easily darkens skin and can turn skin black if allowed to come into contact with it. Care should always be taken to ensure that the correct protective equipment is worn. Prolonged contact with skin can cause burns and severe eye damage can be caused by exposure to Nitric Acid Silver.

In addition to the synonym Nitric Acid Silver, Silver Nitrate is also sometimes referred to as AgNO3, its chemical formula, or Lunar Caustic, its ancient name given by early alchemists.
