Compounds of Silver Course Instructor: Dr. Atul Kumar Singh Assistant Professor Department of Chemistry M. L. Arya College, Kasba Purnia -854330 India
Silver Nitrate (Lunar Caustic) Molecular formula: AgNO3 Method of Preparation it is prepared by heating silver with dilute nitric acid
Properties it is a colorless crystalline compounds It is soluble in water and alcohol Melting point : 212 oC It is decomposed by light therefore stored in colored bottles. On heating above 212 oC, it decomposes to silver nitrate and oxygen
When heated at red hot it decomposes to metallic silver . Reaction with Phosphate
Reaction with Sulphides Reaction with Chromates
Reaction with Thiocyanates . Reaction with Sulphates
Reaction with Thiosulphates White ppt. of Ag2S2O3 which gradually changes to black due to hydrolysis
