Adding Piranha Solution as a new acid(oxidizer)/pyrochem (post your thoughts!)

[TDHooligan]

i don't think it needs a massively complicated reaction series. but i do think it is an interesting, well known, and spooky enough chemical to be an acid with genuinely special effects.

idea: it could be poured on the floor, and standing in it when it's sufficiently concentrated will apply a sizzling DoT that steadily escalates in damage.
