SILVER CYANIDE

CAS NO: 506-64-9
EC/LIST NO: 208-048-6

Silver cyanide is the chemical compound with the formula AgCN.
Silver cyanide is a white solid that precipitated upon treatment of solutions containing Ag+ with cyanide, which is used in some schemes to recover silver from solution.
Silver cyanide is used in silver-plating.

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

Silver Cyanide, CAS 506-64-9 in bulk quantity.
Silver Cyanide is an off-white powder insoluble in water commonly used for research and as an ingredient in silver plating.
Cyanide is an optimal complexing agent—which increase the solubiliy of metal salts— because of its ease to chemically manipulate and elegant white color it yields.
When a metal with lower electrode potential is added to silver cyanide, silver ions displace the metal’s atoms and provide a strong adhesion to the coating.

By recognition that silver cyanide is the formula AgCN.
Ag+ is formed with the solids of these white solutions with cyanide.
This precipitation was used from the solution.
Silver cyanide is used in silver plating.

Its structure consists of -[Ag-CN] chains, in which silver (I) and other d 10 distinctive linear binary Ag + ions are bridged with cyanide ions.
These chains are then packed into hexagons +/- 1/3 of the "c" meshes with the center chains.
This will be with the structure adopted by the high temperature polymorph of copper(I) cyanide.
The silver-carbon and silver-nitrogen bonds in AgCN are both ~2.09 Å, indicating cyanide head-to-tail disease.

Silver cyanide is the general name of hydrocyanic acid and metal salts derived from this acid.
All of them are severely poisonous.
The most important are sodium cyanide and potassium cyanide.
They are obtained by passing a mixture of ammonia (NH3) and CO gases over heated dry carbons in industry.
HCN (Hydrocyanic acid) is a very volatile liquid with the smell of bitter almonds.
Silver cyanide boils at 28 degrees Celsius.
Its solution in water is very weak acid. Cyanide and its compounds can be produced by chemical means, as well as by some plants and animals.
There are many plants, bacteria, and insects that naturally produce cyanide.
Cherries, almonds, apricots, peaches, plums, beans, potatoes, radishes, cabbage, turnips, broccoli and corn naturally produce cyanide compounds.

Many types of cyanide are consumed in different industries.
A large part of the produced HCN is used in the production of chemicals, and the remaining part is used in the production of NaCN.
Both AgCN and KAg(CN)2 have been used in silver plating solutions since at least 1840, when the Elkington brothers patented a silver plating solution for their recipe.

Silver Cyanide is generally immediately available in most volumes.
High purity, submicron and nanopowder forms may be considered.
American Elements produces to many standard grades when applicable, including Mil Spec (military grade);
ACS, Reagent and Technical Grade;
Food, Agricultural and Pharmaceutical Grade;
Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards.
Typical and custom packaging is available.
Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Highly crystalline silver cyanide (AgCN) was synthesized at room temperature using acetonitrile (CH3CN) as a source of cyanide ion (CN⁻).
The in-situ generation of CN⁻ was assisted by the CCN bond breaking of CH3CN.
The reaction was found to be catalyzed by vanadium pentoxide (V2O5) and hydrogen peroxide (H2O2).
The process was very simple and effective one as it was possible to extract the white precipitate of AgCN simply by filtration method.
The overnight standing of the whole reaction mixture resulted in the 100% conversion of AgNO3 to AgCN.
The most significant aspect of the process was that it did not involve any poisonous cyanide compounds like potassium or sodium cyanide;
KCN or NaCN.
Further, it also did not lead to the formation of any hazardous waste.
The present synthetic approach was thus regarded as an alternative and greener route for preparation of pure AgCN directly from AgNO3.

our Selectra silver cyanide is recognized for its chemical characteristics with a silver content of 80.3% minimum.
Silver cyanide comes as white crystals.
Like all the products in the Selectra range, our silver cyanide has been selected for its use in electrolytic surface treatment.

Silver Cyanide, Powder, Purified is also known as Argentous cyanide and often used in silver-plating.
Silver Cyanide is known to be a white solid that is created after treatment of certain solutions containing cyanide.
The Purified Grade describes chemicals of good quality where there are no official standards and is normally limited to inorganic chemicals.

Silver cyanide is a chemical compound of silver and cyanide.
Silver is a metallic element with the chemical symbol Ag and atomic number 47.
Silver cyanide occurs naturally in its pure, free form, as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.

Silver Cyanide is used as lining of autoclave which is used in medicine, silver plating and protective coating reagent and as additive of non-precious metals, precious metal, analytical reagent.
Silver cyanide is also used for electrofacing of electrical contact and engine bearings of airplane.
Silver cyanide can be used to produce Oxalonitrile.

The structure of silver cyanide consists of -[Ag-CN]- chains in which the linear two-coordinate Ag+ ions are bridged by the cyanide ions, typical of silver(I) and other d10 ions.
This is the same binding mode as seen in the more famous case of Prussian blue.
These chains then pack hexagonally with adjacent chains offset by +/- 1/3 of the c lattice parameter.
This is the same as the structure adopted by the high temperature polymorph of copper(I) cyanide.
The silver to carbon and silver to nitrogen bond lengths in AgCN are both ~2.09 Å and the cyanide groups show head-to-tail disorder

Silver cyanide appears as a white to gray odorless tasteless powder that darkens on exposure to light.
Insoluble in water.
Toxic by skin absorption through open wounds, ingestion and inhalation of dust.
Toxic oxides of nitrogen are produced in fires.

Highly crystalline silver cyanide (AgCN) was synthesized at room temperature using acetonitrile (CH3CN) as a source of cyanide ion (CN−).
The in-situ generation of CN− was assisted by the Csingle bondCN bond breaking of CH3CN.
The reaction was found to be catalyzed by vanadium pentoxide (V2O5) and hydrogen peroxide (H2O2).
Silver cyanide was very simple and effective one as it was possible to extract the white precipitate of AgCN simply by filtration method.
