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 ...
Prussian white, also known as Berlin white or Everett's salt, is the sodium end-member of the totally reduced form of the Prussian blue in which all iron is present as Fe(II). It is a sodium hexacyanoferrate of Fe(II) of formula Na 2 Fe[Fe(CN) 6]. [29] Its molecular weight value is 314 g/mol. [29]
Ferroxyl indicator, or rust indicator, is a solution containing potassium hexacyanoferrate(III), phenolphthalein and sodium chloride. It turns blue in the presence of Fe 2+ ions, and pink in the presence of hydroxide (OH −) ions. It can be used to detect metal oxidation, and is often used to detect rusting in various situations.

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.
It is also called hexacyanoferrate(III) and in rare, but systematic nomenclature, hexacyanidoferrate(III). The most common salt of this anion is potassium ferricyanide , a red crystalline material that is used as an oxidant in organic chemistry .
Sodium ferrocyanide is a common anti-caking agent. Specialized applications involves their use as precipitating agents for production of citric acid and wine. Specialized applications involves their use as precipitating agents for production of citric acid and wine.
Sodium dithionite is usually used as a reducing chemical in such experiments (E°' ~ −420 mV at pH 7). Potassium ferricyanide is used to determine the ferric reducing power potential of a sample (extract, chemical compound, etc.). [11] Such a measurement is used to determine of the antioxidant property of a sample.
