Sodium cyanide and hydrogen cyanide are both extremely toxic compounds that contain cyanide ions or molecules. However, there are some key differences between the two:
1. Chemical formula:
– Sodium cyanide: NaCN
– Hydrogen cyanide: HCN
2. Physical state at room temperature:
– Sodium cyanide: Solid
– Hydrogen cyanide: Gas
3. Solubility in water:
– Sodium cyanide: Highly soluble
– Hydrogen cyanide: Soluble
4. Reactivity with acids:
– Sodium cyanide: Reacts with acids to release hydrogen cyanide gas
– Hydrogen cyanide: It is an acid itself (a weak acid)
5. Toxicity:
– Both are extremely toxic, but hydrogen cyanide is considered more dangerous due to its gaseous state, which allows for easier inhalation and rapid absorption through the lungs.
6. Uses:
– Sodium cyanide: Used in gold and silver extraction, electroplating, and as a precursor to the synthesis of other chemical compounds.
– Hydrogen cyanide: Used in the production of plastics, synthetic fibers, and pesticides. It was also used as a chemical weapon in the past.
Both sodium cyanide and hydrogen cyanide are highly dangerous and should be handled with extreme caution. Exposure to either compound can lead to rapid poisoning and death. It is crucial to follow proper safety protocols and have appropriate training when working with these substances.
