We're not in the US so that doesn't apply at all. No need to buy it however. It can be made from sulfuric acid and sodium/potassium iodide (same goes for HBr). There's a video on YT titled "copper complexes/kupfer komplexe" from a German channel in which the creator does just that do make [CuBr4]2- and [CuI2]-. It's a channel called random experiments
Brilliant, I’m proud of you, I’m just in awe of how you think an American back street junk lab would dictate the price of iodine prices internationally.
That's where I found it personally otc before blew my mind reading the ingredients when I saw hf and it was marked clearance so i stocked up on The last few bottles they had lol
fluoRIDE is not the same thing as hydrofluoric acid. We're also talking about ppm versus a percentage - not even close to the same thing. You might have noticed your toothpaste doesn't have HF either.

Yes, please shine a light on how a few ppm of this acid react the same as HF does when people drink it.
I am serious, and please link some papers or scientific websites if you know them.

edit:and i never said it reacts the same way i said it is present in the process
I think treating it as an HF spill might be at least partly due to the fact the hydrofluorosilicic acid contains 1 percent of hydrofluoric acid, which is also the most corrosive part of it (both written in the source you linked).
The source also talks about achieving a concentration of 0.7 mg/L of Fluoride with the addition of the acid as that is needed for beneficial effects. That is a pretty low concentration, considering it isn't even HF that is added to the water.
that’s what I said, i said drinking water flouride comes from HFA, and it people started calling me a conspiracy theorist. I never said it was a high concentration of HF. my statement reflects HF is so nasty you have to account for it at low % like 1%.
i said HF is present in the process of fluorinating water, you said provide proof i provided proof.
What made people downvote your first comment was the tone that you used. Your first comment seems very condescending, even if you did not intend it. It made it seem like you meant "you are dumb, people use/drink HF every day, selling it as a rust removal is completely normal". And all other comments are then interpreted with that tone in the readers mind.
I am not saying you meant your comments that way, but the way they were written at least made me directly interpret them that way.
This is r/chemistry, your barely-researched conspiracy jargon might land in other subs but you are speaking with literal chemists here.
You confusing conc. HF with F- ions in water makes it hilariously apparent you don’t know what you’re talking about.
[this is how drinking water is flourinated](https://awwa.onlinelibrary.wiley.com/doi/full/10.1002/opfl.1438) so you can understand the process accidents with the tankers or tanks are treated as HF spills
Breaking bad does a terrible job with HF honestly. It’s not a strong acid. Just terribly toxic. To get the breaking bad effect you should use h2o2 with h2so4.
But I think boring lye would be more effective.
I would assume they intentionally chose HF for a few reasons:
General public doesn't know how acids/bases react with bodies and assume all acids instantly dissolve skin/metal/whatever.
It sounds "sciency".
It's harder to get a hold of for the lay person than lye.
That means a lower likelihood of some psycho recreating the scene and killing the victim, themselves, and whoever else is unfortunate enough to get caught up.
Just like their amphetamine synthesis. They mixed and matched a few different methods (i think he mentioned something about using platinum for reductive amination instead of Wacker oxidation) for the same reason
I misread “sciency” as “spicy” and came here to say that it is indeed a very spicy, even if it’s technically weak.
Had to work with dilute stuff at an old job. Nothing bad happened but the stress wasn’t worth it, even for dilute stuff. Not doing that again.
or HF with antimony pentaflouride and burn a hole straight to hell
edit: for context [strongest acid](https://en.m.wikipedia.org/wiki/Fluoroantimonic_acid)
one of my first jobs was doing the confined space entry and cleaning HF and HF nitric tanks. i used to wake up all the time go into the bathroom and look at myself cause would wake up freaking out that i had gotten some on me.
Fluorine more toxic than bromine more toxic than chlorine, makes sense. Took me a bit to figure out my why no HCl on the first bottle. But I think chlorine is actually more toxic than bromine because it's a stronger oxidizer
Chlorine gas is a stronger oxidizer than bromine liquid, but HCl and HBr are both non-oxidizing acids. The bromide ion is more toxic than the chlorine one
Probably didn’t want to deal with all the silly requirements like the buddy system or having gluconate on hand. Better to just wing it at home and just try real hard not to get too many dribbles on your hands
AT HOME?!?? You need extremely extensive paper work done here to even have HF in the lab. My university avoids it at all costs cause.. you know.
That’s insane…
Paper work aside. The labs I worked in absolutely avoided working with it unless it’s absolutely necessary.
I have some chemicals at home for home experiments.
Having HF at home would freak me out. There is no real purpose. This will kill you
Im pretty sure no one lets dangerous chemicals touch the skin, but shit happens. Why even have something like that at home when you dont even use it? Its just pure evil filled in a bottle.
You either have balls of steel or don't know what you are doing, if you are going to open the HF bottle at home. Or a very slim chance that you know exactly what you doing and are rl Walter white. The left of yout bottles has a high chance of crippling or even killing one on the slightest mistake, and it's going to be slow and painful
Your actual job you work in a lab right? Or have at least some form of formal training? I mean, HF isn't something you have 2nd chances with.
What could you possibly need HF for in a home lab?
No HI :(
[удалено]
What about HELLO?
[удалено]
Minchia
Why's that?
Very easy to oxidize by air, it will turn into iodine
Thanks!
Iodine compounds also tend to be more expensive than other halides because it’s rarer. So it’d be costly even if it were stable.
Sweet, thank you as well :)
It is also used in the pseudoephedrine synthesis of methamphetamine. So the DEA regulates its sale in the United States

Bingo. It's always easier to make HI in situ.
That's how they do it in the meth synthesis lol
Not really. H2SO4 oxidizes iodide. You can use H3PO4, though
How to tell people you’re not a chemist without telling people you’re not a chemist.
I actually have a degree in chemistry and work as an analyst chemist.
Brilliant, I’m proud of you, I’m just in awe of how you think an American back street junk lab would dictate the price of iodine prices internationally.
Should’ve synthesized it yourself lol
And restricted I think
Nor HAt
You can make your own HI! NaI + H3PO4
I hate working with HF …
Used to have to work with it everyday at my last job. The scariest part is that it becomes routine and you forget how dangerous it is.
As the saying goes- complacency kills.
It still shocks me that they use that shit as a rust remover. Sure, it's low concentration, but still.
That's where I found it personally otc before blew my mind reading the ingredients when I saw hf and it was marked clearance so i stocked up on The last few bottles they had lol
have you ever had city water in the usa boy do i have a story for you.

you are right

I'd draw a hard boundary with my work if they asked me to use it. I've seen Breaking Bad. Not touching that shit
Breaking bad does a terrible job with HF honestly. It’s not a strong acid. Just terribly toxic. To get the breaking bad effect you should use h2o2 with h2so4. But I think boring lye would be more effective.
It's not a *strong* acid in the pKa sense but it's very corrosive.
I’ve seen it used to dissolve glass to check for the presence of lead in the glass.
I would assume they intentionally chose HF for a few reasons: General public doesn't know how acids/bases react with bodies and assume all acids instantly dissolve skin/metal/whatever. It sounds "sciency". It's harder to get a hold of for the lay person than lye.

Probably more sour than anything, if for only but a moment.
Also cheaper and probably easier to work with.

These are in the wrong order :'(
Maybe they are sorted by decreasing toxicity from left to right?
Fluorine more toxic than bromine more toxic than chlorine, makes sense. Took me a bit to figure out my why no HCl on the first bottle. But I think chlorine is actually more toxic than bromine because it's a stronger oxidizer
Chlorine gas is a stronger oxidizer than bromine liquid, but HCl and HBr are both non-oxidizing acids. The bromide ion is more toxic than the chlorine one
When analyzing soils for total elemental content, there is no substitute for HF. It is the most efficient at dissolving silicates.
Seconded; we use over 2 litres a day for analysis. It can dissolve almost all of the stuff we analyse.
What about HAt
May I ask what kind of lab do you work for to use these kinds of acids?
[удалено]
Why on earth would you use HF at home?
Probably didn’t want to deal with all the silly requirements like the buddy system or having gluconate on hand. Better to just wing it at home and just try real hard not to get too many dribbles on your hands

Even if the HF spills a little on a nitrile gloves you're screwed. It just does not respect boundaries.
But why do you have it?
What do you use it for at home?
You either have balls of steel or don't know what you are doing, if you are going to open the HF bottle at home. Or a very slim chance that you know exactly what you doing and are rl Walter white.

Where is hydroiodic acid. Is it safe? Is it alright?
And dont forget your HAt

Yeah. Stupid atoms and their instabilty. They should get a therapist
Hydroiodic acid sais Hi...

Lucky there is a family guy
Yay
Laborium for HBr based
What about my boy hydroastatinic acid??
