ferrocyanide
Ferrocyanide is a chemical compound that contains iron and cyanide ions. Its formula is K4[Fe(CN)6], indicating that it is a coordination complex where iron is surrounded by six cyanide groups. Ferrocyanide is often found in the form of a bright yellow salt known as potassium ferrocyanide, commonly used in various applications, including as a food additive and in the production of blue pigments.
In industrial settings, ferrocyanide is utilized in processes such as electroplating and as a stabilizer in certain chemical reactions. It is important to note that while ferrocyanide contains cyanide, it is generally considered safe in its stable forms and does not release toxic cyanide gas under normal conditions.
