Sulphuric acid is not _that_ dangerous, particularly
if dilute.
Well, *any* acid is non-dangerous if sufficiently diluted. :-)
Just compare, say, anhydrous acetic acid (which is *quite* nasty stuff)
to white vinegar.
Mind you, I once had a long argument with a medical
doctor who tried
to convice me that hydrochloric acid is toxic.
Which it is, in the sense that most "toxic" materials are.
I wonder what he thought was in my stomach?
And I wonder what you think ulcers are? HCl *is* rather nasty stuff,
and stomach lining is rather special, to (among other things) withstand
that toxicity.
