Merely strong dilute, surely? Concentrated would oxidise quite
quite a lot of the cyanide on the way out!

Apparently, that method was used on ships against rats, had to
be done in the hold (cyanide is very light), and the electricity
had to be off.

And how executions were done in some American states , some will
remember the film(s) I Want To Live ! which in both the 50's original
and 80's remake show the bag of cyanide being lowered into the acid
container situated below the condemned fairly graphically.
