Sodium ferrocyanide is the sodium salt of the coordination compound of formula [Fe(CN) 6] 4−. In its hydrous form, Na 4 Fe(CN) 6 · H 2 O (sodium ferrocyanide decahydrate), it is sometimes known as yellow prussiate of soda. It is a yellow crystalline solid that is soluble in water and insoluble in alcohol. The yellow color is the color of ...
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 ...
The sodium fusion extract is made alkaline by adding NaOH.To this mixture, freshly prepared FeSO 4 solution is added and boiled for some time and then cooled. A few drops of FeCl 3 are added and Prussian blue (bluish green) color forms due to formation of ferric ferrocyanide along with NaCl.
The formation of Fe(III)-EDTA (FeY) − can be described as follows: FeSO 4 ∙7H 2 O + K 2 H 2 Y + 1/4 O 2 → K[FeY(H 2 O)]. H 2 O + KHSO 4 + 5.5 H 2 O (1) [8]. Iron chelate has also been used as a bait in the chemical control of slugs, snails and slaters in agriculture in Australia and New Zealand.
[Fe(CN) 6] 3− + e − ⇌ [Fe(CN) 6] 4−. This redox couple is a standard in electrochemistry. Compared to main group cyanides like potassium cyanide, ferricyanides are much less toxic because of the strong bond between the cyanide ion (CN −) and the Fe 3+. They do react with mineral acids, however, to release highly toxic hydrogen cyanide ...
[6] Cyanogen azide is a primary explosive, although it is far too unstable for practical use as an explosive and is extremely dangerous outside dilute solution. [7] [8] Its use in chemistry has been as a reagent prepared in situ for use in the synthesis of chemicals such as diaminotetrazoles, either in dilute solution or as a gas at reduced ...
