: DeIonized water contains no Sodium, Calcium, Magnesium, or any other ions
: good, or bad, in it.  When you drink the water it is devoid of salt.

(followups pruned even more)

Anyone who consumes lab chemicals or solutions is just plain stupid.
While you might think it's a worthwhile saving to sweeten your tea with
BDH sucrose off the lab shelf, consider the consequences if the last
person to dip a spatula in had failed to remove traces of potassium
cyanide from it.  Or imagine drinking punch made with liquid from the
lab ethanol Winchester someone had accidentally refilled with methanol.
(It has happened.)

And don't imagine that your DI water tap hasn't seen active service
in or near some quite noxious solutions...
