potassium ferricyanide CAS# 13746-66-2

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is  Potassium ferricyanide which has developed particularly rapidly in recent years. Do you know about  Potassium ferricyanide?

The official answer:  Potassium ferricyanide is an inorganic substance with the chemical formula K3[Fe(CN)6], commonly known as red blood salt and potassium red blood salt, with a molecular weight of 329.24. It is a red crystal, soluble in water, with yellow-green fluorescence in an aqueous solution, and contains the ferricyanide ligand ion [Fe(CN)6]3-.

Potassium ferricyanide was discovered by the German chemist Leopold Gmelin in 1822, and the composition and crystallisation of potassium ferricyanide were successfully determined by the German chemist Robert Wilhelm Bentham in 1846. The main applications are in photographic paper, pigment, tanning, printing, pharmaceutical, fertiliser, mordant, electroplating, paper, steel and other industries. The central atom of the substance is the iron ion (Fe3+), the ligand is the cyanide ion (CN-) with a coordination number of 6. The inner boundary is the ferricyanide ion {[Fe(CN)6]3-} and the outer boundary is the potassium ion (K+).
