Cyanides are chemical compounds that contain the cyano group, which consists of a carbon atom triple-bonded to a nitrogen atom (–C≡N). They are known for their high toxicity and can be found in various forms, including sodium cyanide and potassium cyanide. Cyanides can occur naturally in certain plants, such as bitter almonds and cassava, and are also produced in industrial processes. Due to their toxic nature, cyanides can interfere with the body's ability to use oxygen, leading to serious health risks or death if ingested or inhaled. Safety measures are crucial when handling cyanides, especially in industries like mining and chemical manufacturing, where they are commonly used.
