Potassium Cyanide definition of Potassium Cyanide in the Free Online Encyclopedia.

potassium cyanide [pə′tas·ē·əm ′sī·ə‚nīd]

(inorganic chemistry)

KCN Poisonous, white, deliquescent crystals with bitter almond taste; soluble in water, alcohol, and glycerol; used for metal extraction, for electroplating, for heat-treating steel, and as an analytical reagent and insecticide.

Potassium Cyanide

KCN, a colorless, hygroscopic, crystalline compound.

Potassium cyanide has a melting point of 635°C and a density of 1.56 g/cm³ at 25°C and is readily soluble in water (41.7 percent soluble at 25°C and 55 percent soluble at 103.3°C). In aqueous solution it undergoes hydrolysis, forming hydrocyanic acid, HCN. The hydrolysis constant of KCN is 2.54 × 10^–5 at 25°C. Potassium cyanide has a great tendency to form complexes, such as potassium ferrocyanide, K₄[Fe(CN)₆] · 3H₂O.

In industry potassium cyanide is produced mainly by neutralizing HCN with potassium hydroxide, KOH. Information on the uses of potassium cyanide can be found in CYANIDE.Potassium cyanide is highly toxic. Its effect on the body and safety rules for its use are discussed in HYDROCYANIC ACID.
