Warning: This experiment deals with dangerous and toxic chemicals. Nile talks about lab safety: https://youtu.be/ftACSEJ6DZA (Copied from the other nitric acid video) Fuming nitric acid is defined as having a concentration of HNO3 greater than 86%. This is much higher than the conventional 68% of common lab nitric acid. The reaction between the nitric acid and the nitrile and latex gloves is extremely exothermic and violent. It is often recommended to avoid using gloves altogether when working with fuming nitric acid unless resistant gloves are available (e.g. butyl rubber gloves or Ansell brand laminated film gloves which were suggested by user Atomosphysica). Regular concentrated nitric acid is still not good to use with latex gloves. Latex offers little to no protection. Nitric acid can quickly penetrate the glove and then irritate skin. Fuming nitric acid is not nearly as common and it is used in much fewer reactions. For example, for the synthesis of high explosives. The high concentration of HNO3 is required in order to nitrate a molecule several times. For example, TNT, or tri-nitrotuluene, is prepared using fuming nitric acid. It is possible to di-nitrate it using concentrated nitric acid, but the third nitration is unlikely to occur, so yield will be zero or uselessly low.

Clear & understandable no-nonsensce explanation.! As a non-English speaking, Chemistry fan I love it.!
Thanks!
Indeed. My English improved even further by watching NileRed :D Clear language and very understandable for English students.
Just a heads up. A native speaker would have probably used "My English has improved". Using "has" changes the phrase from simple past tense(an action that happened in the past and is done) to present perfect tense. Present perfect tense is used to indicate a past action that has consequences that still effect you in the present. Because your improved English is helping you in the present but happened in the past, you want to use present perfect tense "has improved".
can you make some concentrated dark matter? ;)
Yeah.....this guy has got it down!!
Superb explanations, highly accurate......very fine quality content.
I am surprised that you don't have the same/better following than "Nurd rage" because your filming of the experiments are superb, the dialogue/your descriptions supercedes that of anybody else on the scientific demonstration scale.
I have only discovered your videos recently but they are all awesome ;-)
more popular than nurdrage well more subscribers and his explanations are excellent for novice or expert alike
Nile Red>nurdrage. Nuff said.
I was literally going to say the same thing. I'm glad you demonstrate the dangers of this concentrated nitric acid extremely well!
@NileRed can i get the nitrogen dioxide from nitric acid with hydrogen peroxide and have 90% nitric acid?
5 years later, Nigel still #1 on youtube for me!!!
Thank you for including the dangers of lab gloves with fuming nitric. I've been burned many times with fuming nitric on bare skin and it never results in much more than a 1st degree burn if washed quickly. I actually proved to a fellow amature chemist what nitric does by placing a tiny drop on the back of one finger for 60 seconds. Felt like lemon juice in a paper cut and did blister, but my finger did not dissolve. Much better to not have burning plastic on your hand!
@christopher vester It might work to make some HNO3, but not like in this video. You need sulfuric acid because it doesn't have much water in it.
+Nile Red thank you i had a large quanity of hcl so i thought i might of been able to put it too use
@christopher vester Unfortunately it is not well suited for this!
BTW, do you think common lab gloves can protect users from conc H2SO4 and conc HCl?
Wan HL ye it definitely will.
Wow, that's way simpler than expected to make fuming nitric acid.
These older videos of yours are still excellent!
Omg pennies! I remember those!
0:01 make sure you use a fumhood. I love my fumhood. my fumhood is used everyday.
Dilution is solution for pollution
I love the way how you explain the experiment ! Thanks for uploading such informative videos ! I hope you will make more and more such clear demonstrative videos in future
All the best !! .. J.R. Ghimire ( From Nepal )
I'm here from the future!
Hey! I must say this was really easy and helpful..I had to increase the temperature though..
It's so easy to learn chem via your channel because school has made this subject boring.
Now just drop some hexamine in there
I really enjoy your videos! Keep up the exceptional work!
Does anyone know where to get Sikagaurd nitric acid?
I can't find it anywhere online or at the store.
Wears gloves while demonstrating that gloves catch fire
hey I was wondering if you could do an extraction of caffeine from different energy drinks and see how close you can get to the amount produced compared to the amount that they say is in the drinks.
Nitric acid vapours are really bad stuff, by my experience. I've dealt with NO2 before, and it stunk strongly, and that was it, but that nitric acid, even when I breathed in a little of the diluted fumes (i did it in the open, but still, air) when checking up on the apparatus, gave me a ather unpleasant headache.
And that's the reason why we hardly ever wore gloves in the chemistry lab at the uni! ;-)
I would highly recommend chilling the sulfuric acid before mixing, or slowly combining the two as the reaction is quite exothermic and under its own heat will decompose the product.
Exceptional content & very clear & concise, great demonstration of the substances ability's & dangers & the equipment functionality during the processing. Well done from the UK.
All I could concentrate on during that video was the smiley beside the beaker on the right.
Vacuum distillation works quite well for this synth.
Absolutly top educative video!! especially the end with the gloves. An enormous like for your job man
yikes
I'm gonna go back to the new version of this vid
I was wondering if calcium nitrate would work just as well, as it is more readily available than the other nitrated salts in my area, not to mention much cheaper
Saw your video! Very informative and pedagogical.
I just have a question. How can you determinate the exact precent of the nitric acid you do?
Seen in other experiments how you put your chemical in a narrow high measuring cylinder and then put a meter in it. I do not know the word because English is not my native language. It looks like a thermometer and it floating in the liquid messuring the dencity.
Would be so happy if a pro helps me. Happy holidays from Sweden
Thanks sir for such a detailed explanation and demonstrations of chemicals often used in chemical experiments. Some of them such as HNO3 esp fuming is really dangerous!
If performing fractional distillation, is 93% sulfuric acid sufficient to produce the fuming nitric acid?
Love your videos! What temp were you shooting for in the head?
bro your explanations are awesome I live and love chemistry your my teacher since I found you
If you put a vigreux column on it would that help the purity in anyway?
Awesome! I love how you narrate and explain your experiments! Keep it up.
Thanks!
what temperature do you have your hot plate on?
could you make sulfuric acid by adding, directly, sulfur to concentrated nitric acid?
+Carlos Henrique Farias de Barros Junior yes
it's also useful for singly substituted organics... you just need to keep the temp low and watch the reaction.
What's in the canister? Well if I told ya I'd have to kill ya hahaha I'm just mucking about as for whats in the canister it's best u don't ask.-smoke-2015
can i use magnesium nitrate?
Excellent video, very clear and well narrated.
Great video (like all of them:) ), but I have a question - will it change anything if I will use this method but without connector between condenser and collecting flask?
+JurineX94 I am not sure what you mean. Like the collecting flask is connected directly to the condenser?
+Nile Red no, with acid dripping straight from condenser to the flask in the open environment :)
@JurineX94 that shouldnt be a huge problem. Except you will do 2 things. A) your HNO3 might absorb water and become less concentrated and B) you will make A LOT of fumes, which can be dangerous.
+Nile Red Thanks :)
Ammonium nitrate does not produce ammonia....i've used it once to make nitric acid and haven't had a single problem. Also great synthesis!
loving that canadian technical glass dude
When greasing the joints could I use Vaseline? will this react with anything in the experiment?
the problem i found when using vaseline is that it melts and runs into your solutions
I use PVC gloves. I didn't try to put it into a beaker and left for a while, but direct contact is safe enough to have time to wash them on hands in the water without any visible damage. PVC is not very elastic and it's not hard to tear them, but they are as cheap as nitrile and handled with caution are fine complement to nitrile ones.
This is a very nice demonstration!
Good show old boy bravo.
Informative and illustratrative tks
can we store that fuming nitric acid??
sorry if this is a bit old, what about PVC Chemical-Resistant Gloves?
Man I absolutely LOVE your videos, but you really should make legal disclaimers in your videos. I'd hate to see you get sued or something
