Sodium cyanide is a compound with the formula Na C N and the structure 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.
An older cyanide antidote kit included administration of three substances: amyl nitrite pearls (administered by inhalation), sodium nitrite, and sodium thiosulfate. The goal of the antidote was to generate a large pool of ferric iron ( Fe 3+ ) to compete for cyanide with cytochrome a 3 (so that cyanide will bind to the antidote rather than the ...

n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
Sodium cyanate is isostructural with sodium fulminate, confirming the linear structure of the cyanate ion. [3] It is made industrially by heating a mixture of sodium carbonate and urea. [4] Na 2 CO 3 + 2 OC(NH 2) 2 → 2 NaNCO + CO 2 + 2 NH 3 + H 2 O. A similar reaction is used to make potassium cyanate. Cyanates are produced when cyanides are ...
