Preparation and uses of Silver chloride and Silver nitrate

Silver Chloride

AgNO3 combines with chloride ions and forms AgCl precipitate.

Properties

  • 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.

Properties

  • 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.
