  2. Sodium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Sodium_ferrocyanide

    Sodium ferrocyanide is produced industrially from hydrogen cyanide, ferrous chloride, and calcium hydroxide, the combination of which affords Ca 2 [Fe(CN) 6]·11H 2 O.A solution of this salt is then treated with sodium salts to precipitate the mixed calcium-sodium salt CaNa 2 [Fe(CN) 6] 2, which in turn is treated with sodium carbonate to give the tetrasodium salt.

    en.wikipedia.org/wiki/Ferric_ferrocyanide

    The iron in this material is all ferrous, hence the absence of deep color associated with the mixed valency. Oxidation of this white solid with hydrogen peroxide or sodium chlorate produces ferricyanide and affords Prussian blue. [23] A "soluble" form, KFe 3+ [Fe 2+ (CN) 6], which is really colloidal, can be made from potassium ferrocyanide and ...

  4. Ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Ferrocyanide

    Ferrocyanide is the name of the anion [Fe 6] 4−. Salts of this coordination complex give yellow solutions. It is usually available as the salt potassium ferrocyanide, which has the formula K 4 Fe(CN) 6. [Fe(CN) 6] 4− is a diamagnetic species, featuring low-spin iron(II) center in an octahedral ligand environment.

  5. Potassium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Potassium_ferrocyanide

    Potassium hexacyanidoferrate(II) finds many niche applications in industry. It and the related sodium salt are widely used as anticaking agents for both road salt and table salt. The potassium and sodium hexacyanidoferrates(II) are also used in the purification of tin and the separation of copper from molybdenum ores.

  7. Cyanide - Wikipedia

    en.wikipedia.org/wiki/Cyanide

    An older cyanide antidote kit included administration of three substances: amyl nitrite pearls (administered by inhalation), sodium nitrite, and sodium thiosulfate. The goal of the antidote was to generate a large pool of ferric iron (Fe 3+) to compete for cyanide with cytochrome a 3 (so that cyanide will bind to the antidote rather than the ...

  8. Sodium cyanide - Wikipedia

    en.wikipedia.org/wiki/Sodium_cyanide

    Sodium cyanide is a compound with the formula Na C N and the structure Na + − C≡N. It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt .
