|If a person was do digest and acid or a base with
a pH of 14 or 1 what would that acid or base do
to their insides? What is the lowest or highest
pH someoen can eat without injury?

That sounds like a good question to research on
It would depend a lot on the
volume of acid or base you ate - if it was only a
microliter ( 1 cubic millimeter), you would
probably be ok, because it would quickly get
diluted with your saliva - but you might have a
tiny wound on your tongue where it hit.
tends to be harder on the skin than acid, in my
experience as a chemist. Acid eats through cotton
lab coats much faster than bases, but bases make
the skin very sore, and they seem to be hard to
rinse off - they feel slimy; but maybe that's just
how they feel even when they're very dilute - I
... Cool! I looked up: "pH 1"
acid concentration - on google, and I found this
It says stomach acid is pH 1 ! So that must
be not too dangerous, since you get it all the way
up to your mouth when you vomit.
medical abstract about some kids who drank lye by
accident - that's sodium hydroxide and probably a
pH much higher than 14 (I don't know why the scale
ends there) :
Stomach acid has a pH of 1, so once in your
stomach,it's not that bad (unless you've got an
ulcer). It's your esophagus that will get burned
(actually, pH 0will burn you even more).
Adding a pH 13 or pH 14solution to a pH 1
solution is a bad idea; the neutralization will
generate a lot of heat, boiling the respective
solutions, and hot acid and base everywhere. It
sort of gives an all new meaning to the term "gut
bomb", because that's literally what might
happen.I don't know what the limits are, but given
that the stomach is already acidic, I would expect
that low pH would be less destructive than high pH.
