Preparation and uses of Silver chloride and Silver nitrate

Silver Chloride

AgNO3 combines with chloride ions and forms AgCl precipitate.


  • AgCl is obtained as a white precipitate
  • AgCl is insoluble in water.
  • It is soluble in aqueous ammonia

action of NH3 with AgCl

Silver Nitrate

In the preparation of silver nitrate dilute nitric acid is used. Silver combines with HNO3 and forms silver nitrate.


  • It is colorless and is soluble in water.
  • On heating AgNO3 decomposes and forms silver, nitrogen dioxide and oxygen.

decomposition of silver nitrate

AgNO3 forms precipitates with chlorides, bromides, phosphates and sulphides. It is extensively used in laboratories.
