Mike, all,

Sulfuric acid certainly WON'T dissolve ALL metals w/in minutes
although it does attack the commonly available metals rapidly.
If one were to adjust their choice of metals for the electrodes
to something like gold, platinum, or iridium, they would find
that these metals are indeed very resistant to corrosion. Of
course, most of us don't have Bill Gate's bank account, so these
metals are obviously beyond most of our budgets ;^) As a side
note, I don't think there's any acid w/ the exception of aqua-
riga (nitric/hydrochloric acid mixture) that will readily dis-
solve the very stable gold or platinum metals.
