Ferrocyanic.

called; as, fulminic acid. Fulminic acid (Chem.), a complex acid, H2C2N2O2, isomeric with cyanic and cyanuric acids, and not known in the free state, but forming a large class of highly explosive salts, the fulminates. Of these, mercuric fulminate, the most common, is used, mixed with niter, to fill percussion caps, ch…

me proportion by weight), but different molecular weights; -- often used with with; thus, cyanic acid (CNOH), fulminic acid (C2N2O2H2), and cyanuric acid (C3N3O3H3), are polymeric with each other.

designating the acid now called hydrocyanic acid, but formerly called prussic acid, because Prussian blue is derived from it or its compounds. See Hydrocyanic.

Pertaining to, or designating, an acid (commonly called sulphocyanic acid) which frms a red color with ferric salts. [Obsoles.]

An alkaloid occuring in the seeds of mustard. It is extracted, in combination with sulphocyanic acid, as a white crystalline substance, having a hot, bitter taste. When sinapine is isolated it is unstable and undergoes decomposition.

A salt of sulphocyanic acid; -- also called thiocyanate, and formerly inaccurately sulphocyanide. Ferric sulphocyanate (Chem.), a dark red crystalline substance usually obtained in a blood-red solution, and recognized as a test for ferric iron.

pertaining to, or designating, an acid, C4H7N3O2, obtained, by the action of the vapor of cyanic acid on cold aldehyde, as a white crystalline substance having a slightly acid taste and faint smell; -- called also ethidene- or ethylidene-biuret.
