Hydrocyanic Acid - an overview ScienceDirect Topics
WebHCN(g, l, s) is hydrogen cyanide, hydrocyanic acid is HCN(aq). Hydrogen isocyanate dissolves in water to form isocyanic acid, and reacts to form metal isocyanates --- or metal cyanates -- depending on the atom to which the metal associates. The trimerisation of cyanate/isocyanate yields cyanuric acid. *edit* your teacher was 100% wrong ... WebThis problem has been solved!
