  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/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.

    2 K 4 [Fe(CN) 6] + Cl 2 → 2 K 3 [Fe(CN) 6] + 2 KCl. This reaction can be used to remove potassium hexacyanidoferrate(II) from a solution. [citation needed] A famous reaction involves treatment with ferric salts, most commonly Iron(III) chloride, to give Prussian blue. In the reaction with Iron(III) chloride, producing Potassium chloride as a ...
