Silver cyanide AgCN PubChem

SILVER CYANIDE is very rapidly decomposed by acids giving off hydrogen cyanide, a flammable poison gas. Soluble in aqueous ammonia, dilute boiling nitric acid, aqueous potassium cyanide solution and aqueous sodium thiosulfate solutions. Subject to explosive instability or violent oxidation under certain conditions. Fusion with metal chlorates, perchlorates, nitrates, or nitrites can cause a

Dissolve Gold and Silver with Cyanide

The addition of gold or silver to an alkaline sodium cyanide solution will cause the gold and silver to react with the cyanide and dissolve into the solution in a process called cyanidation. This process is more frequently referred to as leaching. As well as reacting with the precious metals, the cyanide will react with iron, copper or zinc that may be in the ore. In order to leach the

Catalytic leaching of silver with ferricyanide-cyanide

Significantly lower silver extraction than gold has been commonly observed in gold-silver cyanidation plants, especially in heap leaching operations. The different mineralogy of gold and silver in the ores is suspected to be the main reason, e.g., the occurrence of low solubility acanthite may result in low overall silver extraction. Leaching of silver sulfide with ferricyanide and its

Solubility of silver cyanide : chemhelp

Q: 1) Calculate the solubility of silver cyanide considering a Kps of 2,2 x 10⁻¹⁶ My A: This one's quite easy, just take the square root of the kps and you have it (approx 1,48 x 10⁻⁸ M). Is this right? Q: 2) Calculate the solubility of the same salt, also considering its complexation between the silver and cyanide ions, and the relation [Ag⁺]/[Ag(CN)₂], given that K₁ x K₂ =5
