Interesting facts about Silver Nitrate


Silver nitrate is an inorganic chemical compound with formula AgNO3. Silver nitrate is basically silver salt, which has powerful antiseptic properties.

German Catholic Dominican friar Albertus Magnus, created silver nitrate in the 13th century. By dissolving the silver, he documented the nitric acid’s ability to separate gold and silver. Johann Shulze used silver nitrate for photography, for the first time in the 17th century.

Properties of Silver Nitrate:

It is a colorless, odorless solid crystalline compound.

Silver nitrate is soluble in water, acetone, ether, ammonia and glycerol.

Melting point: 209.7 Degree Celsius, boiling point: 440 Degree Celsius.

Molecular weight: 169.872 g/mol.

It has bitter, metallic taste and it is not flammable. It is an oxidising agent.

Preparation of Silver Nitrate:

Silver nitrate is prepared by adding silver in nitric acid in the presence of fresh air.

3Ag + 4HNO3 (cold and diluted) -> 3AgNO3 +H2O +NO

Ag + 2HNO3 (hot and concentrated) -> AgNO3 + H2O +NO2

Silver Nitrate Uses:

Acts as precursor to other silver compounds: Silver nitrate is combined with halide salts of potassium or sodium for forming insoluble silver halide in situ in photographic gelatine, which is then applied to polyester or tri-acetate strips, while making photographic film.Silver nitrate reacts with chloride, bromide and iodine to produce white, cream and yellow colored solids. Silver nitrate is also used in preparing some silver-based explosives through a precipitation reaction, such as the fulminate, acetylide or azide.
