Cyanide

A cyanide is apound that contains the group CN. This group, known as the cyano group, consists of a carbon atom triple bonded to a nitrogen atom.. Inanic cyanides, the cyanide group is present as the anion CN .Soluble salts such as sodium cyanide and potassium cyanide are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile

CDC Facts About Cyanide

Cyanide gas is most dangerous in enclosed places where the gas will be trapped. Cyanide gas evaporates and disperses quickly in open spaces, making it less harmful outdoors. Cyanide gas is less dense than air so it will rise. Cyanide prevents the cells of the body from using oxygen. When this happens, the cells die.
