The Prof is the Chuck Norris of Chem, and the Fluorine expert is the Steven Segall of F Chemistry. F as in Fluorine of course! Very well done and informative, as I am ever fascinated by this evil yet very necessary element.
This extra footage is golden. As someone who got a BA in Chemistry in undergrad (but left for less harrowing pastures), it's really interesting for me to see some of the more technical aspects of the lab work. I get to relive and recall the practicalities as well as learn about the more technical scientific concerns at work!
@odysseus9672 Electrolysis. We can reverse reactions by applying current. There is only one chemical way to synthesize it but it is not practical: 2 K2MnF6 + 4 SbF5 = 4 KSbF6 + 2 MnF3 + F2. It is produced by electrolysis of saturated potassium fluoride solution.
Ah, you know of that reaction "discovered" by I believe Dr. Barrett? While not practical, it is the only way to chemically produce fluorine without STARTING with fluorine. All the components can be synthesized from fluorine "salts".
For some reason, my computer skips or something and I can't understand what he's saying at the same part of the video every time I've seen it (even when I re-load it). What sort of sorbent is in the sorbent trap to keep the fluorine out of the vacuum pumps?
i always thought that fluorine was the most reactive element. could someone correct me? cos all of its reacted and its impossible to find the gas as unreacted!
@KlaxonCow An easier way to think of it is that it is like a patina of rust that protects the rest of the metal from reacting, except in this case it is nickel being protected from fluorine instead of iron from oxygen.
I love your videos. =) One reaction I've always wanted to see would be the combination of Fluorine and Francium. F+Fr -> FFr To make Francium Fluoride. The ultimate chemical reaction... XD Unless you could get your hands on some Ununennium.... What do you say? =)
@TheFounderUtopia It was explained briefly in the main video. Basically, the fluorine does react with the nickel the first time that it's introduced into the container. But in reacting with the nickel, it forms a stable protective layer on the surface of the container, which won't thereafter react with any more fluorine. That is, to put it crudely, you let it react until it's "all reacted out" and can't react anymore - then it becomes a useful container, as it'll no longer react with it.
Can* not will form a passivation layer. If you just fill it with fluorine it'd ruin it. You gotta use a very slow flow of the gas diluted with a secondary inert gas to allow just the surface to react then you decrease the inert ones flow as you increase the fluorine till that's all that's going in to test it.
Id love to see some Fluorine be fed some Potassium metal and some yellow Phosphorus - now that would be two very exciting reactions :) PLEASE............
One of the questions should’ve been, is flouring in tap water the cause for dampening our view of more things that happen on this planet? Blocking certain vibrational frequencies that are there making up physical things but most can’t perceive.
Your comment is in the realm of metaphysics, not science. Science doesn't deal with subtle vibrational frequencies of the "energy" of consciousness. Those involved in metaphysics claim that fluoride is absorbed by the pineal gland dampening awareness. But this is a chemistry/science channel.

Thank you for the awesome videos!
thanks for great video!
@KlaxonCow
I see, thanks for explaining! :)

that is a lovely tie
Why is the bond between fluorine atoms so weak? Shouldn't they have a much lower energy even with a nonpolar covalent bond?
did my PhD in fluorine chemistry, it was fun
i always thought that fluorine was the most reactive element. could someone correct me? cos all of its reacted and its impossible to find the gas as unreacted!
@@AshlynnLupe thanks for the prompt reply :D
Oxygen would be almost as reactive as fluorine if it didn’t form passivation layers with almost everything it touches.
@tybo09 I believe he says soda lime.
Leicester yay! :D

What do you say? =)
Unfortunately no one has created enough francium to see with the naked eye without it exploding due to the sheer radioactivity.
Thanks a lot =) (did it post twice, it's not working again grr)
@LizzyAston flourine is indeed the most reactive element, but that doesn´t mean you couldn´t find it unreacted...
Indeed. It does occur native trapped in Fluorite from Wölsendorf.

Why doesn't the Flourine react with the Nickle container? I don't recall Nickle being one of the elements that the Prof said it doesn't react with.
It forms a fluoride passivation layer

I actually read the original comment as a NOKIA container 😂😂😂, now THAT would be a an interesting reaction!!!

PLEASE............
And how do they know that the carbon-fluorine bonds give those interesting properties to drugs?
It biologically increases the drugs permeability to cellular membranes.
He's trying to sap and impurify our precious bodily fluids.

That guy looks like Austin Powers...and he;s just as cool.
lol

This is a science video, go elsewhere tinfoil hat loonatic
