A cyanide will become decomposed and eliminate nitrogen gas, while the residue is charred.
Place one ounce of cyanide of potassium into the bottle and pour in enough dry sawdust to cover the lumps of poison.
Then, opening the clip, run through more cyanide solution and then water, so as to wash the gold-carrying liquor thoroughly into the beaker.
There is no hot water, no sterilising, no cyanide gauze even, but iodine saves many lives, and we have plenty of it.
When tested by cyanide of potassium the gold in the ore often changes into iron pyrites.
Both enzymes were insensitive to cyanide but sensitive to hydrogen peroxide, properties characteristic of iron-containing superoxide dismutase.
Cyanogenesis in animal-plant interactions: cyanide compounds in biology.
We propose that double metal cyanides might have acted as an important prebiotic catalyst.
