Okay, I am seriously crazed by any sort of implications that I have suggested
any procedure that was potentially very dangerous.

And I want to get some serious chemistry understanding going on here.

The bottom line is that "flouride" by itself, while no pussy cat, is not
crazily dangerous.  However, CONCENTRATED HF is.   Note the casual reference
to the term CONCENTRATED.

Specifically, as pH goes down, Flouride goes from the ionized salt to the
protonated form, HF.  Even this, by itself is no more dangerous than HCl,
Hydrochloric Acid, which is sold as toilet cleaner, in every grocery store.

What does get dangerous is when the HF concentration gets high enough to form
the dimer, (HF)2, which is damn dangerous, However, you risk averse, please
make very careful notes, there is no concentration of Ammonium Biflouride in
water, that can create any of the dimer, (HF)2!

Which is why I recommended the use of Ammonium Biflouride, not
HF.(Hydrofluoric Acid)

So, go back to sleep, and try not to drink the stuff, or get it into open
wounds, and eyes, and if it does get on your skin, try to rinse it off within,
say, 10-15 minutes.

And find something else, that actually helps us all get our jobs done, and
quit sweating the details.

Yours in chemistry,

Rudy Sedlak
