And while regular fuming nitric acid can be scary and dangerous, RFNA is excessively more so. Add to that the fact that hydrazine is very toxic, throw in some dense clouds of NO2, and what you get is one incedibly scary hypergolic mixture that will kill you even if by some freak chance it doesn't set fire to you and your surroundings.

Pro tip: while using teflon tape, one should wind the tape in the same direction as the object to be sealed is spun during instalation, also it should be wound from where the threads will finally end up to where they first engage (think like fish scales).

[@alexpotts6520]

I think you're talking about chlorine trifluoride? There have been some proposed uses for it, but the problem is ClF3 is so dangerous that it's liable to damage the rocket, either physically from the explosive reaction with the fuel, or chemically if it starts reacting with bits of rocket. So it's a trade-off - you get higher energy density from your fuel/oxidiser mixture, but you impose extra constraints on the rocket design. Nitric acid burns more controllably, and in addition it passivates many metals which protects the fuel chamber from chemical attack. It's normally a better option unless you really need the highest energy density possible.

[@MatthijsvanDuin]

nobody was talking about chlorine trifluoride

[@crisdekker8223]

I got my information from a very interesting book by a rocket fuel industry insider: library.sciencemadness.org/library/books/ignition.pdf by a guy named John D. Clark. In it he describes the experimental road taken to find the standard liquid fuel combination IRFNA/UDMH, the U standing for unsymmetrical. On the german C-stoff/ T-stoff he writes: "... peroxide is not only a monopropellant, it's also a pretty good oxidizer. And Walter worked out a fuel for it that he called "C-Stoff." (The peroxide itself was called "T-Stoff.") Hydrazine hydrate, N2H4-H2O ignited spontaneously when it came in contact with peroxide (Walter was probably the first propellant man to discover such a phenomenon) and C-Stoff consisted of 30 percent hydrazine hydrate, 57 of methanol, and 13 of water, plus thirty milligrams per liter of copper as potassium cuprocyanide, to act as an ignition and combustion catalyst. The reason for the methanol and the water was the fact that hydrazine hydrate was hard to come by - so hard, in fact, that by the end of the war its percentage in C-Stoff was down to fifteen. The Messerschmitt 163-B interceptor used C-Stoff and T-Stoff. " Check out the PDF if you're into chemistry and things that go boom, very interesting. As for ClF3, he also writes about that, but another great source for that is the series "Things I won't work with" by Derek Lowe, specific entry: blogs.sciencemag.org/pipeline/archives/2008/02/26/sand_wont_save_you_this_time (note the title of the article) The whole series is a delight of horrors :)

[@kdawg3484]

6:35 Me: "Oh, I bet it's passivating it." ...a few seconds later..."Awwwww, yeah, go me." Passivation is a really interesting thing. You could do a whole video on how different materials actually stop corroding in the presence of stronger and/or more concentrated acids, oxidizers, etc. even though that seems counterintuitive. And I don't see any videos on KZbin that actually explore passivation chemistry in detail. Here's an example you might consider using from us chemical engineers that's rather important in industry. A very common process from removing H2S and/or CO2 from gas streams is absorption with an amine such as MEA, DEA, or MDEA mixed with water. Amine plants are full of places with corrosion potential. You would probably expect H2S to be the bigger corrosion threat in the absorption column, but that's not actually true. It's usually CO2. Both of them react with the iron in the column which corrodes the steel. However, the iron sulfide layer formed from the H2S forms much quicker and adheres much more strongly than the FeCO3 layer from CO2. And once a solid FeS layer is formed, it actually protects the steel from further corrosion. So for H2S, we actually DESIGN the column to corrode and form that passivating FeS layer to PROTECT against further corrosion. With CO2, you have to take a completely different approach, because FeCO3 just continuously sloughs off, and you can lose a column much faster in the presence of CO2 because of that. Google "h2s passivation amine column" to read more.

[@stephenjacks8196]

We boiled a 1 inch steel cube in Nitric acid for 72 hours for a required corrosion test. It passed, ferric oxide passivates the surface. Thats why our Nitric Acid drums were made of steel.

[@GraceWhip]

Dude thank you for writing this. I've been stuck on a homework problem for my ChemE reactor design class and this just helped me connect the dots!

[@trevorx7872]

This is close to the reason aluminum doesn't rust: it does, except that the aluminum oxide just sticks to the metal, forming a protective layer. It's really cool.

[@SolarMillUSA]

DUDE. I have been down a rabbit whole on surface energy, surface activation, and PASSIVATION for the past 4 months and you're right there is SOOOOO little content to go with, especially on passivation. If you find some good videos to watch, please let me know. I know citric acid and nitric acid can be used to passivate SS, but it seems like other acids like muriatic can be used to re-activate it? Not clear if that accurate, but I'm surprised it's not an acid-base thing and would like to learn more. Phosphoric acid seems to be king for corrosion protection on most ferritic metals, but doesn't necessarily put them in a passive state. And since most coatings and finish prefer to bond to an active surface would I want to passivate the phosphated surface or should I keep it active before priming? I HAVE SO MANY QUESTIONS and this is after months of reading and watching.

[@a.v.y8331]

this is absolutely why certain extremely corrosive substances are specially stored in vessels that you wouldn't intuitively expect at first glance. for example, extreme fluorinating agents are stored in steel drums, despite being very vulnerable to fluorine, because the fluorine almost instantly scorches the interior of the drum with a fluoride layer, rendering the inside completely inert to fluorinating agents. I think passivating is not a very widely published topic because it's mostly insider industry information that has no real value being publicised. like, no layperson or even chemistry professor really needs to know how to store 1000t of heavily corrosive, almost 100% pure substance, but certain industries have to know. so, they mostly figure it out through their own r&d, confer the specifications to the manufacturers for their vessels, and then just use it as is without publishing it publicly because there's no real reason why anyone else would really need to know how to store the exact same substances. and, even if people DO need to know, they'd usually just look for how to store x specific substance, rather than take an interest in a field of study known as passivating in the first place. passivating is not really a theoretical and experimental science, it's a highly practical one, which means no one is testing how MANY materials can store a given corrosive substance, or how many substances can a given material store - it's mostly just industrial plants/labs testing for the best material to store the given corrosive substance and then running with the best one

0:20 To make make explosives with nitric acid (benzene based) you need to mixed it with concentrate nitric acid and concentrate sulfuric acid. It’s for the “electrophilic aromatic substitution” (EAS): The sulfuric acid reacts whit the nitric acid to form a NO2+ kation and a HSO4- anion. A Benzene electron rich ‘pi-bound’ will react as an nucleophile and add NO2 to his hexane form and form a cyclohexadienyl kation. HSO4- anion must react as an Brönstedt base and needs to eliminate a proton of the cyclohexadienyl kation to recover the aromatic form. I hope I don’t get in trouble whit this reaction 🙄

Dr. Tim Root, an Ophthalmologist has a video where he demonstrates the effects of strong acid on the eye, and he also found that damage does not usually extend to the deeper layers. The eschar (dry charred area of skin formed after a burn) isn't easily attacked by acids, and their reaction will usually stop once it's formed, much like the passivation you encountered with the copper. He also repeated the experiment with a strong base and found that it attacked the eschar as its formed and will react until it's expended itself or makes it through the other end of the pig eye he was testing it on.

I was using fuming nitric acid to dissolve a zinc coating in the lab the other day and was wondering if/how gloves would protect me at all. Good thing I didn't get any acid on me!

[@bluevortex7992]

That's a great all around video on making fuming nitric acid but what mostly amateurs seemed to forget is keeping the sulfuric acid in excess guarantees more and stronger in concentration nitric acid!

[@maxbarnard7165]

Love your videos. You should make a video concerning some of the pathways of a chemist bachelor’s, and yours maybe. I wonder if you are making these videos as a result of not being able to find chemistry work? Very interested, and it would help me decide if I want to remain as a chemistry major.

The reflection of the new lab looks great in the round bottom flask. :)

[@MrTony3696]

You've stepped up your camera game, well done sir.

[@diethylcd]

You can't precisely measure concentration of nitric acid because of no2 contamination,try bubbling dry air into it to remove excess no2 (takes a while) and measure concentration again

[@ethanmye-rs]

He's also measuring with a graduated cylinder, which isn't exactly accurate.

[@Quintinohthree]

ethan It's the best accuracy you're going to get anyway.

[@pietrotettamanti7239]

Guys, there are volumetric flasks. They're the best for this kind of work. A properly used volumetric flask along with an analytical scale and temperature control can give you a density with 3 accurate decimal numbers.

If I remember right, RFNA was most often paired with Aniline dye as the fuel in rockets.

[@TheIdeanator]

You want crazy rocket tests? Cody's Lab is just the collab for you!

[@kaithecrow9931]

You probably wont see this but when ever im having a bad day or i need to sleep i watch you thank you for that

[@forest-195]

I read this as "Making fun of nitric acid" and immediately clicked.

[@trulyinfamous]

I have two suggestions for future videos. Since spring is here, I would like to see you extract latex from dandelions. Another suggestion is the extraction of Coniine from Poison Hemlock. Since Nurdrage hasn't been posting every frequently anymore, I think you will be a great substitute.

[@qbasic16]

At first I read "Making fun of nitric acid" 🤣

[@AlexChangYuan]

Bravo! I bought 500ml of fuming nitric acid from a chemistry store in China 20 years ago, and tested putting one drop on the back of my hand. After 2 secs, the pain was intolerable and I had to wash it off. As reference, I can withstand the same test with H2SO4 for 50 secs(the acid burns through skin around 45 secs), regular HNO3 for 20 secs. Maybe it's bc, like you explained, the skin on the back of the hand is much thinner. When I saw you doing the skin test I thought you must have super-human capability LOL

0:19 high explosives you say? Demonitized.

[@zach11241]

I always wondered why the skin turned yellow. Back in my college days, I got a tiny bit of Nitric Acid on my thumb. It turned yellow, and after a few days, the skin that had colorized fell off leaving behind a small scar I still retain to this day.

[@tylerwilson4951]

Hey NileRed, I have been watching your videos almost every night lately during my wind down time. Great stuff. You should consider brewing a beer for your edible chem series. I have been thinking about dabbling in homebrewing for a while and your videos are inspiring me to finally do it. Thanks for your consideration, take care!

[@leddaudet2350]

Can you make a video about purifying denaturalized ethanol in order to get rid of benzalkonium chloride?

[@paulwchumak]

Hey, love your videos. I know nothing about chemistry but have always wondered about natural liquids and the difference between them. It might be interesting to do a video about all the natural liquids: water, oil/fat, acids, mercury/other liquid elements, alcohols. Just a thought!!

[@kaseymathew1893]

"This stuff will make your gloves burst into flames, so you should handle it with your bare hands."

[@Fabler21]

Yeah.. Because your bare hands aren't made out of rubber

[@Lorentari]

"The nitrile reacts quicker but may be easier to remove" took you longer to say than the time it took to start burning xD

[@kevsonkeyboard]

[@Ahmed-vs1ui]

Do u know why it didnt melt hos finger??

"It worked out better because you could see the heating flask" *Covers with foil*

[@Jborrelli101]

You help me fall asleep I’ve watched hours of you and I learn something new every time

[@loristratostx7390]

Very good video! I understood everything! I have two questions for you. Can I use hydrochloric acid (10%) or acetic acid (80%) instead of sulfuric acid? And if you make nitric acid by this way you get K2SO4 or KHSO4?

[@atlas8827]

No, these acids won't work.
