kaliumcyanide
Potassium cyanide, sometimes referred to by the synonym kaliumcyanide, is an inorganic salt with the chemical formula KCN. It typically appears as white to colorless crystalline solids and is highly soluble in water. In aqueous solution, cyanide ions strongly bind to metal centers and can disrupt cellular respiration in living organisms by inhibiting the enzyme cytochrome c oxidase. This makes potassium cyanide acutely and rapidly toxic.
Industrial production is typically achieved by reacting hydrogen cyanide (HCN) with potassium hydroxide, yielding potassium cyanide
Primary uses include gold and silver ore processing through cyanide leaching, where cyanide dissolves precious metals
Safety and handling: potassium cyanide is extremely toxic if ingested, inhaled, or absorbed through the skin.
