Platinocyanide, also known as tetracyanoplatinate (IUPAC), cyanoplatinate, or platinocyanate, is a polyatomic ion with the molecular formula [Pt(CN) 4] 2−.The name also applies to compounds containing this ion, which are salts of the hypothetical platinocyanic acid (sometimes platinocyanhydric acid).
Cyanide is quantified by potentiometric titration, a method widely used in gold mining. It can also be determined by titration with silver ion. Some analyses begin with an air-purge of an acidified boiling solution, sweeping the vapors into a basic absorber solution. The cyanide salt absorbed in the basic solution is then analyzed. [47]
Potassium hexacyanidoferrate(II) is produced industrially from hydrogen cyanide, iron(II) chloride, and calcium hydroxide, the combination of which affords Ca 2 [Fe(CN) 6]·11H 2 O. This solution is then treated with potassium salts to precipitate the mixed calcium-potassium salt CaK 2 [Fe(CN) 6 ], which in turn is treated with potassium ...
Cyanogen is typically generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: . 2 Hg(CN) 2 → (CN) 2 + Hg 2 (CN) 2 Or, one can combine solutions of copper(II) salts (such as copper(II) sulfate) with cyanides; an unstable copper(II) cyanide is formed which rapidly decomposes into copper(I) cyanide and cyanogen.
The cyanate ion is an anion with the chemical formula OCN −. It is a resonance of three forms: [O − −C≡N] (61%) ↔ [O=C=N − ] (30%) ↔ [O + ≡C−N 2− ] (4%). Cyanate is the derived anion of isocyanic acid , H−N=C=O, and its lesser tautomer cyanic acid (a.k.a. cyanol), H−O−C≡N.
