I am trying to understand why higher concentrations of H+
speeds up cyanide action.
As far as I know, what kills the individual is the cyanide anion (CN-
), not the cyanide acid (HCN).
Let's say we have a cyanide salt dissolved in a glass of water and then we add an acid (or we can imagine an empty stomach that is extra acidified):
Global process: KCN(aq)
As we can see, the addition of ions H+
reduces the ammount of ions CN-
and favours the formation of HCN. What I am missing?
Another ilustration: In gas chambers, one makes the following reaction, to produce HCN(g)
2HCN + K2
Why not ingest KCN(aq)
Obs1: Sorry for my english
Obs2: I am not trying to kill anyone, just trying to understand the process.
