Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. A minor tautomer of HCN is HNC, hydrogen isocyanide. Hydrogen cyanide is weakly acidic with a pK a of 9.2. It partially ionizes in water solution to give the cyanide anion, CN −. A solution of hydrogen cyanide in water, represented as HCN, is called hydrocyanic acid.

Hydrogen cyanide is a highly toxic clear to pale blue liquid or gas with the odor of bitter almonds. It melts at -14 C and boils at 25.6 C. It is miscible in water or ethanol and is slightly soluble in ether. Its water solution, called hydrocyanic acid, is a weak acid.

Trivalent gold-cyanide solutions also have been used in jewelry plating to deposit very bright, adherent layers up to about 5 microns thickness. Electrolytes for these processes operate typically over a pH range from about 2.5–3.0.
