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.〔Andreas Rubo, Raf Kellens, Jay Reddy, Joshua Wooten, Wolfgang Hasenpusch "Alkali Metal Cyanides" in Ullmann's Encyclopedia of Industrial Chemistry 2006 Wiley-VCH, Weinheim, Germany. 〕 KCN is highly toxic. The moist solid emits small amounts of hydrogen cyanide due to hydrolysis, which smells like bitter almonds.〔http://www.smh.com.au/news/world/suicide-note-reveals-taste-of-cyanide/2006/07/08/1152240534587.html〕 Not everyone, however, can smell this; the ability to do so is a genetic trait. The taste of cyanide has been described as acidic 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.〔(【引用サイトリンク】url=http://www.hindustantimes.com/nm13/the-only-taste-cyanide-is-acrid/article1-118408.aspx )〕 ==Production== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「potassium cyanide」の詳細全文を読む スポンサード リンク
