Hydrogen cyanide | Description, Uses, Effects, & Facts
hydrogen cyanide, a highly volatile, colourless, and extremely poisonous liquid (boiling point 26° C [79° F], freezing point -14° C [7° F]). A solution of hydrogen cyanide in water is called hydrocyanic acid, or prussic acid. It was discovered in 1782 by a Swedish chemist, Carl Wilhelm Scheele, who prepared it from the pigment Prussian blue.

Cyanide Formula
Calcium cyanide, often known as black cyanide, is an inorganic chemical with the formula Ca (CN)2 that is the calcium salt of hydrocyanic acid. Although rare, the pure form is a white solid; commercial samples might be black-grey in colour. It is easily hydrolyzed to release hydrogen cyanide (even in humid air).

Cyanide
A cyanide is any chemical compound that contains the cyano group (C≡N), which consists of a carbon atom triple-bonded to a nitrogen atom. Cyanide specifically is the anion CN-.Many organic compounds feature cyanide as a functional group; these are called nitriles in IUPAC nomenclature (for example, CH 3 CN is referred to by the names acetonitrile or …
Potassium Cyanide | KCN | CID 9032
The excretion of (14)C-labeled cyanide in rats exposed to chronic intake of potassium cyanide was studied in rats exposed to daily intake of labeled potassium cyanide in the diet for 6 weeks. Urinary excretion was the main route of elimination of cyanide carbon in these rats, accounting for 83% of the total excreted radioactivity in 12 hr and 89% of the …
Cyanide: Characteristics, Structure, Properties, Uses, and …
The chemical properties of cyanide are listed below. Cyanide ion is a good nucleophile due to the presence of a large electron cloud of unpaired electrons. It reacts with substituted alkyl halides and displaces the halogen atom, forming nitriles. RX +CN− →RCN +X− R X + C N − → R C N + X −.

Cyanide (inorganic) compounds
Potassium cyanide: 1.52 kg/m 3. Chemical properties. Cyanides are a group of compounds based on a structure formed when carbon and nitrogen are combined. When cyanide combines with chemicals from the metals groups it forms simple salts. Calcium cyanide, potassium cyanide, and sodium cyanide all will liberate hydrogen cyanide (which is …
Sodium Cyanide | NaCN | CID 8929
Toxic by skin absorption through open wounds, by ingestion, and by inhalation of dust. Sodium cyanide is a cyanide salt containing equal numbers of sodium cations and cyanide anions. It has a role as an EC 1.15.1.1 (superoxide dismutase) inhibitor. It is a cyanide salt, a one- carbon compound and a sodium salt.
Cyanide
Chemical compounds, which release cyanide are called cyanogenic compounds. Usually, cyanides are bound to sugar molecules in plants in the form of cyanogenic glycosides, and they defend the plant against herbivores. Cassava roots (which are also called Manioc) are an important potato-like food grown in tropical countries (and …

SODIUM CYANIDE | CAMEO Chemicals | NOAA
Deliquescent. Soluble in water. Slowly decomposed by water and very rapidly by acids to give off hydrogen cyanide, a flammable poison gas. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Cyanide gas will be created in 12 minutes.
