Hexacyanoferrate (III) of potassium (red prussiate of potash, ferricyanide of potassium [1], geksatsianoferriat potassium) — complex K3 ferri-compound [Fe(CN)6].
Ferroprussiate (Geksatsianoferratt (II) potassium, potassium ferrocyanide) — complex K4 ferro-compound [Fe(CN)6] existing usually in the form of K4 trihydrate [Fe(CN)6] · 3H2O. Ferroprussiate - light yellow crystals with tetragonal lattice. Let's dissolve in water, it is practically not dissolved on air, ethanol, pyridine, aniline, ethyl acetate. Potassium geksatsianoferroat diamagniten.
The generic name "yellow blood salt" has appeared because before it received by alloyage of waste from slaughters (in particular, blood) with potash and iron sawdust. It, and also yellow color of crystals, have caused the name of connection.


Component of the tinting, bleaching, strengthening, weakening solutions in photos, electrolyte in hemotronny devices, component of electrolytes in galvanoplasty, reagent for detection of Fe2 + (see above), Li + Sn2+, and also as strong oxidizer.

In soil science use for qualitative test of gleying (salts of bivalent iron).
Potassium geksatsianoferroat it is applied
• at production of pigments,
• silk dyeing,
• in production of cyanic connections, ferrite,
• in production of color paper,
• as component of the inhibiting coverings
• at cyanation staly, for allocation and utilization of radioactive caesium, etc.
• in analytical chemistry as reactant for detection of some cations
• in the food industry potassium ferrocyanide is registered as food additive of E536 interfering caking and balling up, for example as additive to sodium chloride, etc.
