Potassium ferrocyanide

Description:

Potassium ferrocyanide, with the chemical formula K₄[Fe(CN)₆]·3H₂O, is a bright yellow crystalline compound commonly known as yellow prussiate of potash. It is a coordination complex consisting of potassium ions and the ferrocyanide ion, [Fe(CN)₆]⁴⁻. This compound is highly soluble in water, forming a deep yellow solution, and is known for its stability and non-toxic nature, making it useful in various applications. It is often employed in the production of pigments, as a food additive, and in the electroplating industry. Additionally, potassium ferrocyanide serves as a reagent in analytical chemistry for detecting certain metal ions. Its structure features a central iron atom coordinated to six cyanide ligands, which imparts unique properties, including its ability to form complexes with various metal ions. Despite its name, it does not contain cyanide in a free form, and its use is generally considered safe when handled properly.
