Potassium hexacyanoferrate (II), also known as potassium ferrocyanide, is a yellow crystalline solid that is soluble in water and forms stable solutions. It is a coordination compound containing a central iron atom surrounded by six cyanide ligands, and it typically crystallizes with three water molecules of hydration.

Applications:

1. Chemical Industry: Potassium hexacyanoferrate (II) is used as a precursor in the synthesis of various iron-based and cyanide-containing compounds.
2. Pigments: It is employed in the production of pigments such as Prussian blue, widely used in paints and dyes.
3. Water Treatment: The compound is sometimes used in water treatment processes to remove heavy metals by forming insoluble ferrocyanides.
4. Electroplating: Potassium ferrocyanide is used as a complexing agent in electroplating baths for the deposition of metals.
5. Laboratory Reagent: It is used in analytical chemistry as a reagent to detect the presence of ferric ions and other metals.

Although relatively non-toxic compared to other cyanide-containing compounds, potassium hexacyanoferrate (II) can release toxic hydrogen cyanide gas when exposed to strong acids. It should be handled with care, using proper personal protective equipment (PPE), and stored in a tightly sealed container in a cool, dry place away from acids and incompatible materials.
