Just be sure to keep the sulfuric acid out of the
cyanide bath! I plate
using a silver anode and silver cyanide and the solution (other than the
bad reaction with acids) is relatively tame.
I still wouldn't want to drink it...
Concentrated sulfuric acid is mostly noteworthy in its appetite for water,
which can cause nasty burns. But fuming nitric acid can do far more
damage, as it reacts with protein. Yet one can purchase very strong bases
Nitric acid is difficult to obtain over here because of the obvious (?)
use in nitrating things.
