WebCyanide is a rapidly acting, potentially deadly chemical that interferes with the body’s ability to use oxygen. Cyanide can be a colorless gas or liquid, such as hydrogen cyanide (HCN) or cyanogen chloride (CNCl). Cyanide can also be a crystal (solid) form such as sodium cyanide (NaCN) or potassium cyanide (KCN).
