Potassium Ferrocyanide 3H20

Potassium Ferrocyanide Trihydrate, also known as potassium hexacyanoferrate(II) trihydrate. It consists of potassium (K⁺) cations and the hexacyanoferrate(II) anion ([Fe(CN)₆]⁴⁻), along with three water molecules (3H₂O) per formula unit.

Chemical Formula: K₄[Fe(CN)₆]·3H₂O

Appearance: Lemon-yellow crystals or as a yellowish-white powder.

 Uses:

• Analytical Chemistry: Potassium ferrocyanide 3H20 is used in analytical methods and assays in chemistry laboratories. It is often used as a reagent in qualitative and quantitative analysis, particularly for the detection and determination of metal ions.

• Anticaking Agent: In food and beverage industries, it may be used as an anticaking agent or flow enhancer in powdered or granulated products. It helps to prevent the formation of lumps and ensures the free-flowing properties of dry food ingredients, such as salt and powdered sugar.

• Deicing Agent: Potassium ferrocyanide 3H20 is known for its potential application as a deicing agent for roads and pavements during winter months. When applied to icy surfaces, it can help to lower the freezing point of water and facilitate the melting of ice, providing safer conditions for transportation.

• Photography: It is commonly used in the photographic industry as a component of iron-based developers.
