How to make fluorine gas at home?

Question

The method should be available at home. No electrolysis or method that has to apply heat. If you got a method of just mix substances that will be good. thank you.

Answer 1

Besides being extremely dangerous in either its pure form or as HF, fluorine is the most active halogen on the periodic table and as such cannot be freed from its compounds. For example if you put some chlorine in water and add this solution to a solution of NaBr in water, the chlorine replaces the bromine, which is less active, and goes into solution as NaCl

Cl2(aq) + NaBr(aq) --> NaCl(aq) + Br2(aq)

Since fluorine is the most active, no other halogen will replace it from its compounds and you are left with having to do electrolysis.

Answer 2

the length of X-F bonds decrease as the product of the charges on A and F increases. Furthermore, the length of X-F bonds decreases with a decreasing coordination number n(2). The number of fluorine atoms that are packed around the central atom is an important factor for calculating the bond length. Also, the smaller the bond angle (

Answer 3

Don t make it at home, you ll most likely die, like other guys noted.
I m an experienced chemist, and I ve never even made it in lab, firstly because it s very dangerous, and secondly, because it s hard to make. I ve only made HF gas once, and probably won t be doing it again. But pure F2 is far more dangerous, even for me (or any of fellow chemists I know).

However, for educational purposes: It s industrially made by electrolysis of KF/HF mixture, because you cannot electrolyse pure HF.
There is also a more difficult way (because of the chemicals used aren t commonly available), but I like it more, since it s pure chemistry, and not electrolysis:


2 KMnO4 + 2 KF + 10 HF + 3 H2O2 → 2 K2MnF6 + 8 H2O + 3 O2↑

and then you use K2MnF6:

2 K2MnF6 + 4 SbF5 → 4 KSbF6 + 2 MnF3 + F2↑

Answer 4

Fluorine is beyond incredibly dangerous. It forms HFl with water making hydrofluoric acid which will etch glass but will also penetrate the skin without much pain and begin to destroy the calcium bone structure causing pain only after serious damage has been done.

Answer 5

Fluorine is extremely dangerous. The discovery of fluorine gas cost several researchers their lives. This is not something to mess with at home.

Answer 6

Fluorine gas is not something that one should make at home. It is exceedingly corrosive. Fortunately there are no simple substances or processes available for making it.

Answer 7

I wouldn't try anything like that. I think compounds like IF(iodine flouride) can actually pentrate into bones and cause irreversible damage, decalcifying bones.
