a. [ Ferri- + cyanic. ] (Chem.) Pertaining to, or derived from, a ferricyanide. [ 1913 Webster ]

Ferricyanic acid (Chem.), a brown crystalline substance, H6(CN)12Fe2, obtained from potassium ferricyanide, and regarded as the type of the ferricyanides; -- called also hydro-ferricyanic acid, hydrogen ferricyanide, etc. [ 1913 Webster ]

a. [ Ferro- + cyanic: cf. F. ferrocyanique. ] (Chem.) Pertaining to, derived from, or designating, a ferrocyanide. [ 1913 Webster ]

ferrocyanic acid (Chem.), a white crystalline substance, H4(CN)6Fe, of strong acid properties, obtained from potassium ferrocyanide, and regarded as the type of the ferrocyanides; -- called also hydro-ferrocyanic acid, hydrogen ferrocyanide. etc. [ 1913 Webster ]

a. [ Hydro-, 2 + anic: cf. F. hydrocyanique. ] (Chem.) Pertaining to, or derived from the combination of, hydrogen and cyanogen. [ 1913 Webster ]

Hydrocyanic acid (Chem.), a colorless, mobile, volatile liquid, HCN, having a characteristic peach-blossom odor. It is one of the most deadly poisons. It is made by the action of sulphuric acid on yellow prussiate of potassium (potassium ferrocyanide), and chemically resembles hydrochloric and hydrobromic acids. Called also prussic acid, hydrogen cyanide, etc. [ 1913 Webster ]

n. [ Hydro-, 2 + ferricyanic. ] (Chem.) Pertaining to, or containing, or obtained from, hydrogen, ferric iron, and cyanogen; as, hydroferricyanic acid. See Ferricyanic. [ 1913 Webster ]

a. [ Hydro-, 2 + ferrocyanic. ] (Chem.) Pertaining to, or containing, or obtained from, hydrogen, ferrous iron, and cyanogen; as, hydroferrocyanic acid. See Ferrocyanic. [ 1913 Webster ]

a. [ Iso- + cyanic. ] (Chem.) Designating an acid isomeric with cyanic acid. [ 1913 Webster ]

Isocyanic acid, an acid metameric with cyanic acid, and resembling it in its salts. It is obtained as a colorless, mobile, unstable liquid by the heating cyanuric acid. Called technically carbimide. [ 1913 Webster ]

a. (Chem.) Pertaining to, or designating, an acid, HNCS, isomeric with sulphocyanic acid. [ 1913 Webster ]

a. (Chem.) Pertaining to, or designating, a yellow crystalline substance (called also perthiocyanic acid), analogous to sulphocyanic acid, but containing more sulphur. [ 1913 Webster ]

a. (Chem.) Pertaining to, derived from, or designating, an acid compound of platinous cyanide and hydrocyanic acid. It is obtained as a cinnaber-red crystalline substance. [ 1913 Webster ]

a. [ See Sulphur, Cyanic. ] (Chem.) Of, pertaining to, derived from, or designating, a sulphacid, HSCN, analogous to cyanic acid, and obtained as a colorless deliquescent crystalline substance, having a bitter saline taste, and not poisonous. [ 1913 Webster ]
