    CAS No.: 151-50-8 Formula: CKN Molecular Weight: 65.11570

    Description

    Potassium cyanide is a compound with the formula KCN. This colorless crystalline salt, similar in appearance to sugar, is highly soluble in water. Most KCN is used in gold mining, organic synthesis, and electroplating. Smaller applications include jewelry for chemical gilding and buffing.
    KCN is highly toxic. The moist solid emits small amounts of hydrogen cyanide due to hydrolysis, which smells like bitter almonds. Not everyone, however, can smell this; the ability to do so is a genetic trait.
    The taste of cyanide has been described as acrid with a burning sensation on the tongue. An Indian man who committed suicide left a hastily scrawled note describing the taste of the fatal toxin, the Hindustan Times newspaper reported. "Doctors, potassium cyanide. I have tasted it. It burns the tongue and tastes acrid," he wrote, according to the paper.
