Sodium cyanide - Wikipedia

Sodium cyanide is a poisonous 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:

SODIUM CYANIDE HAZARD SUMMARY Sodium Cyanide

* Sodium Cyanide may cause the thyroid gland to enlarge. * Exposure can damage the nervous system and cause changes in the blood cell count. * Repeated lower exposures can cause nose discharge, nosebleeds, and sores in the nose. IDENTIFICATION Sodium Cyanide is a white powder (like salt) with a faint almond-like odor.
