A solution of hydrogen cyanide in water, represented as HCN, is called hydrocyanic acid. The saltsof the cyanide anion are known as cyanides. Whether hydrogen cyanide is an organic compoundor not is a topic of debate among chemists, and opinions vary from author to author.
The most hazardous compound is hydrogen cyanide, which is a gas and kills by inhalation. For this reason, an air respirator supplied by an external oxygen source must be worn when working with hydrogen cyanide. [11] Hydrogen cyanide is produced by adding acid to a solution containing a cyanide salt.
Hydrogen cyanide gas was strongly suspected. [85] [86] In 1995, a device was discovered in a restroom in the Kayabachō Tokyo subway station, consisting of bags of sodium cyanide and sulfuric acid with a remote controlled motor to rupture them, in what was believed to be an attempt by the Aum Shinrikyo cult to produce toxic amounts of hydrogen ...
Cyanide preparation to be opened and used only by trained personnel". Zyklon B ( German: [tsyˈkloːn ˈbeː] ⓘ; translated Cyclone B) was the trade name of a cyanide-based pesticide invented in Germany in the early 1920s. It consists of hydrogen cyanide (prussic acid), as well as a cautionary eye irritant and one of several adsorbents such ...

The hydrogen cyanide gas chamber is considered to be the most dangerous, most complicated, most time-consuming and most expensive method of administering the death penalty. [ 34 ] [ 35 ] [ 36 ] It is also notoriously impossible to halt once initiated, which has occurred in the case of stays, such as in the case of Burton Abbott .
The gas cloud, composed mainly of materials denser than air, stayed close to the ground and spread in a southeast direction affecting the nearby communities. [32] The chemical reactions may have produced a liquid or solid aerosol. [35] Laboratory investigations by CSIR and UCC scientists failed to demonstrate the presence of hydrogen cyanide ...
