We used HF in one of the production lines, all of the guys I met who worked on the line had some exposure. The cure is to inject calcium gluconate under the skin at the point of exposure multiple times. If you ever walked under the reactors you didn't look up you looked for holes in the floor to see where there was leaking. As an undergrad I worked at an incinerator, we received some barrels from the EPA that were mislabeled on the manifest. The sampler thought it was a pretty safe and routine chemical and sampled it without the full suit. He didn't notice the exposure right away, but said it itched when he got home. It progressed to actual pain, they had to amputate the thumb for an exposure so small he didn't notice it. BB is frustrating for someone with chemistry knowledge to watch, you have to treat it as a fantasy series. I played a game called the many deaths of Jessie where I'd count the number of times he should have died from how he handled the chemicals. The first I saw was when he was pouring HF from a jug into a container and it was splashing everywhere early in season 1. There were many deaths in that, especially once they upscaled the process and they were sticking their heads into and even climbing into the reactors.

@user-dl8zj6ko8n

3 ай бұрын

Even if a person exposed to HF receives immediate emergency medical attention and intensive supportive medical care with calcium gluconate that does not guarantee that the patient will survive HF exposure some patients who survive the initial HF exposure still end up dying up to two weeks after the initial exposure

2:00 cool they actually got Walter White

In 10th grade earth science class some kids thought it would be funny to spray hydrochloric acid in my face, mostly in my eyes. (bullies obviously) It is one of the most extreme pains i have ever felt. The teacher got me to the eye wash station very quickly, maybe 45 to 60 seconds had passed. i washed my eyes out for around 15 min before i went to the nurses and continued to rinse my eyes for another 10 as i waited for me mum to bring me to the doctor. at the doctors after looking at my eyes said that if i had waited any longer to rinse my eyes that they would have deflated. the recovery took about 1 to 1.5 months. oddly enough the only problem that continued after recovery was an odd colour blindness. Colours would change as i looked at them if other colours were brought near the colour i was looking at. to this day i can still see colours wrong. Acid is scary!

This man is the legendary Martyn Poliakoff. The cleverest man I ever met and the best teacher by a country mile. An absolute star.

I work in hazardous waste, I have been since 2012. HF is one of two chemicals that legit scare me (the other one being crystallized picric acid). Most of the chemicals I have labpacked in my time are hazardous, yes, but most of the chemicals are easily managed, providing you have a bit of common sense. The two exceptions are the two I just mentioned.

Not neccesarily, it depends on its strength.. although you'll never get the James Bond situation where someone falls in a tank of acid and dissolves immediately, there are numerous examples of attacks where blindness and burns happen within a matter of minutes. That's why if you get acid on you, or are attacked with an unknown substance, its essential to immediately rinse yourself with water as much as possible.

The deadly part about Hydrofluoric Acid is the reaction of Fluorine with calcium and magnesium in the victims body. It penetrates the skin easily and starts bonding with calcium and magnesium causing hypocalcemia and hypomagnesemia. The effects are more sinister than Hydrochloric/Sufluric acid burns, since it can take a while for symptoms to manifest. Tissue necrosis is often delayed and due to the lack of symptoms and therefore lack of treatment it can be more devastating than in the more immediate acting acids.

Yup, I think this is the real bit of info that the video is missing, it's what makes HF so dangerous. Also, I think HNO3 would have been a better control than H2SO4 given that sulfuric causes heating via desiccation which obscures the acidic effects.

It also explains why the HF chicken leg looks pale after it has been exposed to HF. Over night the HF has infiltrated the whole leg binding with Ca/Mg and other ions, while the HCl and Sulfuric acid were limited to mostly surface reactions.

It's too bad that they didn't test to see if the chicken bone was more fragile in the leg that was in HF

Also the fact that fluorine can leach calcium ion means that it can leach calcium ions from the heart leading to a heart attack.

So I'm designing a sci race that uses hydrofluoric acid as part of their respiratory process to liquify silica. Would it be reasonable to have an organ or system of organs that can protect against the acidity like the human stomache protects itself with mucus?

They told me in chem school that HF dissolves the bone and not the flesh and that makes it more dangerous because you won't feel it burning. But I guess it was just a legend

I was told that HF reacts with Ca2+ Ions to CaF2, that are needed for information transition in the nervous system at the end of a neuron. I did work in a lab, where ~30% HF was filled in buckets. The safety sheet said that previously it was assumed that at least 30% of the skin surface need to be touched for it to be lethal, but latest reports have shown lethal accidents as low as 5-10% skin surface. People working there longer said, that each worker would have an accident within 6 years with an average stay of 4-6 weeks in the hospital. The acid is not strong - it is so small that it can diffuse through the skin. One worker told me he had an accident in the morning and noticed the black spot in the evening, because it did not hurt.

I love the quote at the end comparing it to dance partners.

Trifluoromethanesulfonic acid and Fluoroantimonic acid are two of the strongest acids known (Hence their name of superacids), would it be possible to do an episode on these, or are they too dangerous to deal with in a lab environment?

The greatest danger is that the poisonous gases could give off or that those two are expensive to use. (For example: 5 grams of Trifluoromethanesulfonic acid costs 70 euros).

@Xz4

Triflurormethansulfonic acid (or Triflic acid) is definitely safe enough to use small amounts of - I've used it in a lab environment before. It's used a lot in organic synthesis because you don't need aqueous solutions (which is useful as water is pretty reactive and can often break down sensitive organic molecules) and its conjugate base (the molecule without an H+) isn't nucleophilic (i.e. doesn't react with positive charges quickly) because it's so big and stable. It's also usually used as a catalyst rather than a reagent, so the amount you need to use is very small. However, using it in larger quantities e.g. the amount of acid used in the video would be very dangerous!

I'm not a chemist, and am rather rubbish at chemistry that's why I'm asking this. A thing that interests me is how is that when you do a controlled experiment on a piece of meat with a very strong acid nothing spectacular happens even after a rather long time, and when you see victims of acid attacks they show severe acid burns and they were attacked by a commercially obtainable acids and not with pure stuff you can use in labs? Does live flesh react in different ways or is it about surface being attacked or about types of acids used?

@SilentSnipest

9 жыл бұрын

I am not quite sure of this myself, but I would be willing to bet that fresh/alive meat has significantly more moisture readily available for the acid to dissolve into. This would make it much more easy for the acid to penetrate the flesh and corrode the structures externally and internally much faster.

So hydrogen ions just weaken bonds in the chicken leg's molecules so fluorine can be bound with them?

@WhyPhi

7 жыл бұрын

The bond between hydrogen and fluorine is weak compared to the bonds fluorine wants to make with other atoms such as carbon. In water, HF undergoes rapid equilibrium where HF+H2OH3O+ + F- To my understanding: If just about any organic molecule gets near the fluoride in solution,, it will attack and form a sigma bond (single bond) which would be highly favored over the H-F rapid equilibrium state.

Why doesnt F- in NaF fluorinate carbon also? NaF is water-soluble yielding an abundance of F- ions in our bodies every time we drink water.

How strong were these concentrations? Would the acids have reacted a lot faster such as justice few minutes if it was more so?
