Potassium ferrocyanide is a compound with formula K4[Fe(CN)6]·3H2O. It is a yellow crystalline salt, which is soluble in water and insoluble in alcohol. Potassium ferrocyanide is also known as yellow prussiate of potash or potassium hexacyanoferrate(II).
Chemical properties[edit]
Potassium ferrocyanide is a coordination compound, which means it has a central metal atom (iron) surrounded by charged particles (cyanide ions). It is not a cyanide salt because the cyanide ions are tightly bound to the iron within the compound. This makes it less toxic than simple cyanide salts.
Uses[edit]
Potassium ferrocyanide has several uses. It is used in wine and food production as an anti-caking agent. It is also used in the production of pigments, and in the process of steel tempering.
Safety[edit]
While potassium ferrocyanide is less toxic than simple cyanide salts, it can release hydrogen cyanide gas if mixed with an acid. Therefore, it should be handled with care.
