Sodium cyanide - Wikipedia
Sodium cyanide is an inorganic compound with the formula Na C N.It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals.It is a moderately strong base.When treated with acid, it forms the toxic gas hydrogen cyanide:
