How to neutralize cyanide??
Adding bleach to a solution of sodium cyanide slowly gives a colorless gas (I tried it). Probably this gas is nitrogen. I did the experiment outside with less than 100 mg of sodium cyanide dissolved in 2 ml of water and a few ml of 5% bleach added. The gas, produced with this, is nearly odorless, there is a faint smell, but not of chlorine....
