Which is more toxic, sodium cyanide or potassium cyanide?
- busterwasmycatLv 73 weeks agoBest answer
the sodium and the potassium only affect the mass per unit (mole or atom/ion) cyanide, and the mass difference is small. It has a trivial effect on the toxicity of the cyanide (if toxicity is defined in terms of mass of the salt).
Obviously, potassium cyanide would require a slightly higher mass to provide the same cyanide content as sodium cyanide, so on the trivial level, the potassium might be able to be called "less" toxic (depending on how you define toxicity).

The effects of potassium cyanide and sodium cyanide are identical and the median lethal dose (human) for potassium and sodium cyanide is estimated at 200–300 mg.
