Preparation of Potassium cyanide: this chemical can be prepared by the treatment of Hydrogen cyanide with Potassium hydroxide:
HCN + KOH → KCN + H₂O

Uses of Potassium cyanide: it is widely used in organic synthesis for the preparation of nitriles and carboxylic acids. It is also used in electroplating, such as jewelry for chemical gilding and buffing. And this product has been used as a killing agent in collecting jars by entomologists. Additionally, this chemical can form water-soluble salts from gold metal in the presence of air in gold mining:
4 Au + 8 KCN + O₂ + 2 H₂O → 4 K[Au(CN)₂] + 4 KOH

When you are using this chemical, please be cautious about it as the following: it is very toxic by inhalation, in contact with skin and if swallowed. And it would liberate very toxic gas in contact with acid. Please keep container tightly closed and do not empty into drains. After contact with skin, you should wash immediately with plenty of soap-suds. Moreover, it is very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.) And this material and its container must be disposed of as hazardous waste. Please avoid release to the environment and refer to special instructions / safety data sheets.
