Description Feedback
Sodium cyanide is an inorganic compound with the formula NaCN. 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. When it is treated with acid, it forms the toxic gas hydrogen cyanide:
NaCN + H2SO4 → HCN + NaHSO4
