Sodium Fluoride

[frosch45]

If you took toothpaste, is there any way that you could get fluoride (F2) gas. I realize there are impurities, which would have to be filtered, and there is only a very small amount in one tube of toothpaste.

 

Any help appreciated...

Well, for one, fluoride is ionic (F-) so it would not be a gas. The stuff in tooth paste is usually Na+ F-.

Next, fluorine gas (F2) is one the most reactive things around (it even reacts with argon) so you would have GREAT difficulty isolating it. Fluorine gas is usually produced by electrolysis and it reacts with whatever it comes in contact with as soon as it is produced.

Which is a good thing because fluorine gas is VERY VERY toxic.

 

Wiki has a good write up on fluorine.

I hope that helps

maybe i wont then

you`d be surprised to know that there`s easily enough in a tube of toothpaste to kill you!

 

And you have to remember that you Cannot use any Glassware towards the end, I have 500g of Ammonium bifluoride here, and a single crystal on a microscope slide will eat a hole half way through it

 

it`s equally adept at Skin or lung linings too.

 

you`r wise to scrap this idea

Do they add fluoride to your drinking water over there on the other side of the big pond YT?

[YT2095]

not in my area no, only Chlorine.

That would explain why the Brits have such awful teeth.

Well... there May actually be Some truth in that non the less.

not being a dental expert (or even the remotest little bit interested in it) I can`t really comment, but then I can rule it out as a possibility either.

it's a general rule of thumb that when you combine the most reactive elements they form the most stable compounds. hence sodium (catches fire in water and sometimes explodes) and fluorine (burns the crap out of skin and reacts even with noble gases) forms sodium fluoride (boring white stuff). And cesium (explodes in air) and iodine (fairly reactive) forms cesium iodide (boring white stuff)
