Hydrogen cyanide (HCN), sometimes called prussic acid, is a chemical compound with the chemical formula HCN. It is a colorless, extremely poisonous and inflammable liquid that boils slightly above room temperature, at 25.6 Â°C (78.1 Â°F).
The relative stability of metal-cyanide compounds and complexes in water (listed in order of increasing stability) is presented below. Free Cyanide Free cyanide refers to the sum of hydrogen cyanide (HCN) and cyanide ion (CN-) in a sample. Free cyanide is bioavailable and toxic to organisms in aquatic environments.
