Potassium ferrocyanide (Chem.), yellow prussiate of potash; a tough, yellow, crystalline salt, K4(CN)6Fe, the starting point in the manufacture of almost all cyanogen compounds, and the basis of the ferric ferrocyanate, prussian blue. It is obtained by strongly heating together potash, scrap iron, and animal matter containing nitrogen, as horn, leather, blood, etc., in iron pots. [ 1913 Webster ]

n. [ Haema- + Gr. ky`anos a dark blue substance. ] (Physiol. Chem.) A substance found in the blood of the octopus, which gives to it its blue color. [ 1913 Webster ]

n. Same as Haemacyanin. [ 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. (Chem.) A compound of hydrocyanic acid with a base; -- distinguished from a cyanide, in which only the cyanogen so combines.

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