What is Silver Nitrate?

With the molecular formula AgNO3, silver nitrate is an inorganic compound in the form of odourless white crystals. Historically, it was once called lunar caustic as ancient alchemists believed silver was related to the moon.


Typical Reactions Involving Silver Nitrate

A common reaction, known to many students around the world, involves suspending a copper rod in a silver nitrate solution. After a few hours, the solution is turned blue as the silver nitrate reacts with copper to generate silver metal crystals leaving copper nitrate (blue) in solution.

2 AgNO3 Cu → Cu(NO3)2 2 Ag

Another well-known reaction involves decomposition of silver nitrate at high temperatures. This reaction becomes particularly prevalent as the temperature approaches its melting point (250 degree Celsius) and will totally decompose at temperatures above 400 degree Celsius. Interestingly, this reaction produces elemental silver (Ag) instead of silver oxide, as it would be expected from the decomposition of metal nitrates.

2 AgNO3(l) → 2 Ag(s) O2(g) 2 NO2(g)


How is Silver Nitrate Made?

Silver nitrate is usually prepared by mixing silver and nitric acid. The reaction produces silver nitrate, water and nitrogen oxide, but the exact ratio varies with the reaction conditions and nitric acid concentration:

Diluted and cold HNO3 solutions: 3 Ag 4 HNO3 → 3 AgNO3 2 H2O NO Hot and concentrated HNO3 solutions: Ag 2 HNO3 → AgNO3 H2O NO2

Silver Nitrate Uses 

Silver nitrate solution is a salt that is widely used in laboratories, industrially and in many everyday products. Popular applications include:

  • Testing for chloride
  • In the production of pharmaceuticals
  • In the medical industry as an antibacterial/antimicrobial, haemostatic, pain reliever and on wounds as a healing agent
  • To prepare certain silver-based explosives such as silver fulminate, azide or acetylide.

Hazards and Dangers

Silver nitrate in its purest form is hazardous, corrosive and dangerous for the environment. It will also stain the skin by darkening it.

It is crucially important that this product is handled responsibly by qualified persons wearing appropriate Personal Protective Equipment (PPE). This includes gloves, eye protection, protective clothing and safety boots or shoes.

In a diluted solution silver nitrate does not warrant any hazardous warning symbols. However, this chemical should still be treated with care. Whether purchasing silver nitrate in solid or solution form, customers should consult the relevant Material Safety Data Sheets (MSDS) for handling and storage information. These are available to download from this page.
