cyanide

listen to the pronunciation of cyanide
Englisch - Englisch
Any compound containing the -C≡N radical or the C≡N-1 anion
hydrogen cyanide, or cyanide gas - a poisonous gas
potassium cyanide - a water soluble poison
A compound formed by the union of cyanogen with an element or radical
{i} lethal poison (Chemistry)
A chemical compound comprised of carbon and nitrogen Cyanide is water- soluble and is used in ore processing solutions to extract gold from crushed rock
One of 11 pollutants of concern, cyanide is a naturally occurring inorganic substance with many industrial uses The major cyanide users are the steel, electroplating, mining, and chemical industries
Cyanide is a highly poisonous substance. a very strong poison (cyanogen type of poisonous gas (19-21 centuries), from cyanogène, from kyanos ( CYAN)). Any chemical compound containing the combining group CN. Ionic (see ion; ionic bond) and organic cyanide compounds differ in chemical properties, but both are toxic, especially the ionic ones. Cyanide poisoning inhibits cells' oxidative (see oxidation-reduction) processes; its action is extremely rapid, and an antidote must be given promptly. Cyanides occur naturally in certain seeds (e.g., apple seeds, wild cherry pits). Cyanides, including hydrogen cyanide (HCN, or hydrocyanic acid), are used industrially in the production of acrylic fibres, synthetic rubbers, and plastics as well as in electroplating, case-hardening of iron and steel, fumigation, and concentration of ores
Any compound containing the -C≡N radical or the C≡N[-1] anion
1 An ion with a -1 charge containing one atom of carbon bound to one atom of nitrogen 2 A compound that contains CN- ions
It is used in the recovery of gold and silver and also as a flotation reagent in the treatment of base metal ores
an extremely poisonous salt of hydrocyanic acid
A powerful poison that is toxic to humans and aquatic life Measured in mg/L or ppm The MCL for cyanideA is 0 2 mg/L or ppm
highly poisonous substance used in the extraction of gold and silver
any of a class of organic compounds containing the cyano radical -CN
cyanide process
A method of extracting gold and silver from their ores with a solution of sodium cyanide
cyanide process
A process of case-hardening iron or steel by immersing it in molten cyanide and then quenching in water or oil
cyanide poisoning
poisoning due to ingesting or inhaling cyanide; common in smoke from fires and in industrial chemicals
cyanide process
A process of extracting gold or silver from ores by treating them with a solution of sodium cyanide or calcium cyanide. or MacArthur-Forrest process Method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide. The process invented in 1887 by the Scottish chemists John S. MacArthur, Robert W. Forrest, and William Forrest includes contacting the finely ground ore with the cyanide solution, separating unwanted solids from the clear solution, and recovering the precious metals from the solution by precipitation with zinc dust
cyanide process
an idustrial process for extracting gold and silver by treating ore with a sodium cyanide solution
carbonyl cyanide
The nitrile CO(C≡N)2
hydrogen cyanide
A colourless, very poisonous, volatile liquid, HCN, used in the production of dyes, plastics and fumigants; it dissolves in water to form hydrocyanic acid and reacts with bases to form cyanides, and with some organic compounds to form nitriles
methyl cyanide
An alternative name for acetonitrile
potassium cyanide
The potassium salt of hydrocyanic acid, KCN; the colourless crystals are soluble in water, and it is extremely poisonous, and is used in electroplating, the extraction of gold and silver from their ores, and in photography
vinyl cyanide
The compound acrylonitrile
A cyanide
cyanuret
calcium cyanide
A gray or black compound, Ca(CN), used to kill insects and rodents
hydrogen cyanide
a highly poisonous gas or volatile liquid that smells like bitter almonds; becomes a gas at around 90 degree fahrenheit and is most dangerous when inhaled; the anhydride of hydrocyanic acid; used in manufacturing
hydrogen cyanide
A colorless, volatile, extremely poisonous flammable liquid, HCN, miscible in water and used in the manufacture of dyes, fumigants, and plastics. It becomes a gas at 26°C
potassium cyanide
a poisonous salt (KCN) used in electroplating and in photography
potassium cyanide
An extremely poisonous white compound, KCN, used in the extraction of gold and silver from ores, in electroplating, and in photography, and as a fumigant and insecticide
sodium cyanide
A poisonous white crystalline compound, NaCN, used in extracting gold and silver from ores and in dye manufacture
sodium cyanide
a white poisonous salt (NaCN) used in electroplating
