Safety Information
Silver sulfate Usage And Synthesis
  • Chemical PropertiesSmall, colorless, lustrous crystals or crystalline powder. Contains about 69% silver, turns gray on exposure to light.Soluble in ammonium hydroxide, nitric acid, sulfuric acid, hot water; insoluble in alcohol.
  • Physical propertiesColorless crystals or powder; slowly darkens when exposed to light; density 5.45 g/cm3; melts at 652°C; decomposes at 1,085°C; slightly soluble in water; dissolves in nitric acid, concentrated sulfuric acid and ammonia solution.
  • UsesSilver Sulfate is a catalyst used in the treatment of wastewater. Also used in the formation of nanostructured metallic layers below Langmuir monolayers.
  • UsesSilver sulfate is used as a catalyst to oxidize long chain aliphatic hydrocarbons in the determination of chemical oxygen demand (COD).
  • PreparationSilver sulfate is precipitated by adding sulfuric acid to a solution of silvernitrate:

    2Ag+(aq) + SO42- (aq) → Ag2SO4 (s) The precipitate is washed with hot water and preparation is under ruby red illumination.

  • General DescriptionOdorless white to gray solid. Sinks and mixes with water.
  • Reactivity ProfileSilver sulfate has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
  • HazardHighly toxic.
  • Health HazardContact with eyes causes irritation. If continued for a long period, ingestion or inhalation of silver compounds can cause permanent discoloration of the skin (argyria).
  • Purification MethodsCrystallise the sulfate form hot conc H2SO4 containing a trace of HNO3, and dilute with H2O while being strongly cooled. The precipitate is filtered off, washed with H2O and dried at 120o. Its solubility in H2O is 0.8% at 17o, and 1.46% at 100o. Store it in the dark.
