In closed opaque plastic or dark amber glass bottles, in a dark place, away from light.Īdding a reducing agent, such as formaldehyde or ascorbic acid will cause it to decompose to metallic silver which can be recycled. Is Ag2SO4 (Silver sulfate) soluble or insoluble in water The answer that Silver sulfate is insoluble (according to the Solubility Rules) or slightly soluble. Silver sulfate precipitates as a solid when an aqueous solution of silver nitrate is treated with sulfuric acid : 2 AgNO 3 + H 2 SO 4 Ag 2 SO 4 + 2 HNO 3 It is purified by recrystallization from concentrated sulfuric acid, a step that expels traces of nitrate.

Ingestion of the compound may lead to argyria. Wear proper protection when handling the compound. Silver carbonate is light-sensitive, decomposition begins in seconds after synthesis under light and tends to stain. This salt is yellow but typical samples are grayish due to the presence of elemental silver. Since silver carbonate is practically insoluble in water, it will precipitate out of the solution, while sodium nitrate will remain in solution.Ģ AgNO 3 + Na 2CO 3 → Ag 2CO 3 + 2 NaNO 3 Projects Silver carbonate is the chemical compound with the formula Ag 2 CO 3. Silver carbonate can be prepared by reacting a mixture of silver nitrate with another of sodium carbonate.

Silver carbonate is sold by various suppliers, but it's not cheap. Silver carbonate will decompose if heated above the boiling point of water. It is poorly soluble in water and organic solvents. Silver carbonate is colorless solid which quickly turns yellow upon exposure to light and finally brown if kept too much in light. No conditions are given for this reaction. Silver carbonate reacts with ammonia to give the explosive silver fulminate.Ĥ Ag 2CO 3 + 4 NH 3 → 4 AgCNO + 6 H 2O + 4 Ag + O 2 Like all other carbonates, silver carbonate will react with acids to give their respective silver salts and give off carbon dioxide.Īg 2CO 3 + 2 HNO 3 → 2 AgNO 3 + H 2O + CO 2
