Potassium dicyanoargentate

Chemical properties

Potassium silver cyanide is a poisonous, white solid made of crystals, which are light sensitive. It is soluble in water and acids and slightly soluble in ethanol. It emits very toxic fumes when heated to decomposition.

Chemical properties

Potassium silver cyanide is a white crystalline solid.

The Uses of Potassium dicyanoargentate

In silver plating.

The Uses of Potassium dicyanoargentate

Silver platingPotassium silver cyanide is used in silver plating and in the manufacturing of antiseptics. It is a versatile bridging ligand and finds use for multidimensional polymer construction.

General Description

White crystals. Poisonous. Used in silver plating, as a bactericide and in the manufacture of antiseptics. Not registered as a pesticide in the U.S.

Air & Water Reactions

Water soluble [Merck].

Reactivity Profile

Potassium dicyanoargentate is light sensitive. Acids precipitate silver cyanide from its aqueous solution. Fusion with metal chlorates, perchlorates, nitrates or nitrites can cause violent explosions [Bretherick 1979 p. 101].

Hazard

Very toxic.

Health Hazard

The primary health hazard is as a cyanide. (Non-specific -- Cyanide, Inorganic, n.o.s.). It is poisonous and may be fatal if inhaled, swallowed or absorbed through the skin. Fire may produce irritating or poisonous gases.

Health Hazard

Potassium silver cyanide is a poisonous, white solid made of crystals, which are light sensitive. It is soluble in water and acids, and slightly soluble in ethanol. It emits very toxic fumes when heated to decomposition. Synonyms for potassium silver cyanide are potassium argentocyanide and potassium dicyanoargentate

Fire Hazard

When heated to decomposition, Potassium dicyanoargentate emits very toxic fumes of cyanide and nitrogen oxides. Avoid light.

Flammability and Explosibility

Not classified

Safety Profile

Poison by ingestion. A severe skin and eye irritant. When heated to decomposition it emits very toxic fumes of CN-, K2O, and NOx. See also CYANIDE and SILVER COMPOUNDS.

Potential Exposure

Potassium silver cyanide is used in silver plating; as a bactericide; and in the manufacture of antiseptics. Not registered for use as a pesticide in the United States

Shipping

UN1588 Cyanides, inorganic, solid, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Incompatibilities

Contact with acid, acid fumes release hydrogen cyanide. Incompatible with water, steam, or when heated to decomposition, emits toxic and flammable cyanide vapors. Potassium silver cyanide reacts with carbon dioxide releasing hydrogen cyanide. Light sensitive. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materi- als, strong bases, strong acids, oxoacids, epoxides. Acids precipitate silver cyanide from its aqueous solution. Fusion with metal chlorates, perchlorates, nitrates or nitrites can cause violent explosions

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations govern- ing storage, transportation, treatment, and waste disposal.
