THE DISCORD : https://discord.gg/AYnAyvePMh I made this video to showcase some explosives that were never seen on youtube : nickel cobalt and copper picrate mainly. anyway have fun ! my videos : https://youtu.be/FYLR5NWHXfY?si=01GTX02W-AC5L2_A https://youtu.be/abDgpmYk4dk?si=jza3TlN-0x3fQ3Bx https://youtu.be/bnPGHNSiijM?si=7tq4m-CZXGl_kpJF Background musics I used in this video : https://youtu.be/WmHnk90fCg8?si=okSkX6go11ZsREc_ https://youtu.be/b6dPHjpZl7A?si=H_kChqOH7P3yXncP https://youtu.be/oKJ2EZnnZRE?si=3gLIFjTMiMbkU6ic https://youtu.be/Ib91lUpV7EM?si=02b2baB_R74KFiq3 #lab #acid #explosion #chemistry #science #tutorial #diy #boom
This is one of the biggest reasons why picric acid isnt used today, even though its a great explosive and its availability is very good, it forms complexes with even metal oxides to make metal picrazes which are way more unsensitive and cant be inside bullet shells so..... and its very easily reduced into even more reactive picramates
Yeah but they're still pretty fun to play with
I love how low quality the equipment is, really makes it relatable
Thanks 🤣😭
I always think others youtubers have so much equipment like vacuum pumps and more. So I'm happy to show the reality of most home chemists :D
Hi Jam Kemist,
Nice video.
I must tell that picrates are for most unknown, so here are some of my information or experimental findings:
1°) Picric acid is a bit a weird compound that can be acidic in two ways involving color change.
a)As you know phenol name comes from the special habit of keton-enol switching so phenol can be seen as a keton on a cyclohexadiene ring.
So HO-C=CH- is also O=C-CH2 (or - C(OH)=CH - can be seen as (-CO-CH2-)
b)Also the nitro group onto an aromatic is not exactly what people think it is; it has a bit its nitronic acid nature and the group next to it plays a role.
So for example TNT has a defined color, sensitivity and mp; but when you add a strong base like NaOH, it is more sensitive and has a deeper orange-red shade.
So CH3-C=C-NO2 (here depicited as a sub part of the aromatic molecule) can be seen as CH2=C-C=N(=O)-OH by a "proton" jump from a "not specifically acidic" CH3 to a more acidic nitronic structure involving an aromatic -NO2 (-N(=O)-OH)
It is not as an usual alkylic nitronic acid obtained from nitroalcanes and NaOH and that turn dark brown-black in microseconds; it is like an equilibrium with less of the nitronic form, what explains the orange-red instead of the dark-brown; but this is sufficient to explain a difference into sensitivity of TNT.
Yellow, Orange, Red, Brown or whatever color, when concentrated looks realy black to a chemist or artist eye.
Here into the case of phenol, there is a much more easy proton jump from the quite acidic HO- group to a keto-nitronic-H orange-red especially if strong base is present.
This must explain the sensitivity to flame observed for your Na picrate and NH4 picrates.
So if you think not too hard and deeply, you will understand that picric acid or picrate with a certain % of sensitiver ketonitronic salt form will make the all batch more sensitive.
I guess the Li(+) must be interesting.
2°)Usually K(+) salts make more anhydrous and sensitive salts... than NH4(+) or Na(+); while stil being a strong alcaline base; it will of course share with sodium an ammonium the nitrophenate-ketocyclohexadiene nitronate color and enhanced sensitivity but boosted by less water of cristallization content.
3°)I did test the reaction of picric acid solution onto hydrazinium hydroxyde and it makes a precipitate of glissening shiny yellow cristals of hydrazinium picrate. The salt is unfortunately not that powerful on its own (I suspect the nitronic form is not that present due to the lack of basicity of hydrazinium hydroxide vs ammonium hydroxide); The salt seems to only sublimate. It was not tested for impact or actuated by a primary. It was tested with Ni(N2H4)3(NO3)2 and Ni(Picrate) as a brown precipitate with less output than the pinky clayish Ni(2+) tris-hydrazino nitrate precipitate (NiHN).
4°)Transition metals like Ni(2+), Co(2+) or Cu(2+) are of course interesting colorfully and chemically speaking ,but they display also some rare hybrid forms like basic picrate salts like Ni(OH)(O-TNB), Co(OH)(O-TNB), Cu(OH)(O-TNB) that may occure during the process, precipitation or hydrolysis with water from the solution.
This doesn't count with the fact copper is a rare metal that can easily express its Cu(+) or Cu(2+) "ambi"-valence; with different colors, sensitivity (to flame, storage, shock), solubilities.
As a final surprise, the possibility of higher valences Cu(3+)(rare), Co(3+), Ni(3+) with also their spicy different colors, sensitivity (to flame, storage, shock) or solubilities.
5°) The test of Aluminium foil (to flame open or folded - open or confined) is of course great and a must for any great chemist; but maybe use the test in the open onto some other metalic surface like an inox (steenless steel); because of the inerent sensitivity of aluminium metal to acids, bases and maybe possible partial formation of Al(Picrate)3, Al(OH)(Picrate)2, Al(OH)2(Picrate) in the warm melting into the melt; or even alumino-thermic oxydo-redox reaction that could happen between Cu, Co, Ni salts...
6°) Very little people knows this but one of the most sensitive picrate that readily happens into the not too suited event of a lab glassware shattering of a TNP solution onto marmor is the calcium salt
2 HO-TNB + CaCO3 --> Ca(Picrate)2 + H2CO3 (H2O + CO2(g))
Keep on enjoying chemistry.

Thanks for this huge comment as always ! I do read them since you seem very educated and give interresting advice. If you have time I have a question :
One of my friend made nickel picrate but his salt was much more crystaline and deep green.
I don't have a picture but would this be explained by the presence of the Ni(II) hydroxide picrate you talked about ?
@@jam_kemist3986
I have no immediate answer to this because I haven't worked with picrates for the two last decades.
I could in some weeks if needed.
But indeed there are two major players here; eather Ni(O-TNB)2 or Ni(OH)(O-TNB) and each may form under different cristalline form depending onto sovent, dissolution, concentration, heat, nucleation, ... so the process makes considerable difference into the final outer-look. Cristallinity may also induce more sensitivity to shock, friction, heat due to cristal lattice deffects lowering locally the activation energy for decomposition, fire, explosion or detonation.
you really need a glassplate for that table, maybe some vinyl flooring in dark color, similar jars and painted jar lids, just that alone would up your production quality massively
I'm working on it ! I have used some ceramic for the table and now building a simple fumehood as well hehe
Nice video. I like your editing style.
I think some sensitivity testing would be a great addition to similar videos in the future.
@@isaacmcginn7923thanks !
Yeah I wanted to test them but didn't had a way to do it precisely so I guess that's for later
new server with @Mryellow and @salt and peroxide ! https://discord.gg/gpntKUgNHm
Ganidinium, Urea and maybe hydrazinium picrate if you are willing to work with that stuff all sound interesting. Hexamine dipicrate might also be possible.
As for metal picrates, I would love to see magnesium, aluminum, manganese, titanium or iron.
All are very good ideas for a pt.3 or/and 4
Seems like I'll have to extend the series further 🗿
@@jam_kemist3986Also some hevier metals would be interesting to see, such as Bismuth, Mercury (if you can get your hands on some) and Barium.
@@jam_kemist3986maybe also try some heavier metals such as Ba, Bi or Hg, there is a whole world of picrates waiting to be explored
@@jam_kemist3986 Don't waste your time, lead picrate is much more powerful (and more stable than other heavy metals salts, like silver picrate). 😉
@@nestorlapin4736 thanks for the tip lol
0:58 ...And some coordination chemistry (BNCP, but with picrate anion lol), hydrazine, maybe guanidine derivatives, urea, hexamine, idk anything else
That's actually a very good idea for a video. Guess I have to do a pt.3 now lol
@@jam_kemist3986 It would be even cooler to place the oxidizer in the coordination sphere for better oxygen balance, but i don't know how do it
@@jam_kemist3986 Uhm... Maybe pentaerythritol trinitrate (or amino derivative) can help
Or dinitrourea/nitramide idk
YouTube isn’t going to like this title. Depending where you live it could be a big deal actually. Just a heads up, great video though!
Just In case I changed it bcz you never know, thanks for the comment anyway ! 🐢
Also, what is the oxidation number of the metals in these salts?
2 for Ni, Cu, and Co, 1 for NH4 and Na
Also try Picrate esters and the proton next to the picrate anion looks so cursed
Itiz wat itiz 🐢
Why are you not ALWAYS wearing glove while handling dangerous chemicals???
I thought you were going to try lead picrate?
I could have but I was trying to demonstrate lesser known ones, I could make it as well as other ones in the future
Your pace is a little fast. I would slow your narrations down about 20%. I believe I would be amiss if I didn't remind you that adding chemicals to a hot beaker on a hot plate like that is MOST ILL ADVISED and I would personally immediately discontinue use of that process. Simple accidents happen and there are things you should never breathe that may result from a mere bump to the elbow and subsequent spill. It would help you a lot to have a cleaner table to use and scrub down all your gear including that hot plate. Just a thought. Contaminants cause all kinds of side reactions you don't want to have to mitigate just for a video, believe me.
i think a lot of chemistry is conducted by adding chemicals to a flask or beaker when its on a hotplate
Thanks for the comment !
And of course the Beaker was cold when I added the chemicals inside so idk what danger you're refering to ?
I also don't really see how would things go from under the beaker to inside but I agree it's a bit messy 😂
Amazing work well done how are you
Thanks a lot I'm pretty fine
@@jam_kemist3986 cool I join you biscorb
@@jam_kemist3986 change all the B in to D to understand
How are you doing
Very nice video more like this
Thanks !
Fulminates next
Hehe maybe If I get some Hg or Ag
Uranium fulminate,
has anyone tried that? Ever?
Picrate esters?
That might be possible but I don't see much information about them, and I'm not sure if they are safe to make the same way esters are usually made (reflux)
I must say y'all are very creative, I've got many answers and suggestions for more exotic picrates so there will definitly be a part 3 but idk if I want to make differant salts, complexes, salts with non metal ions like hydrazinium, or esters as you mentionned

Большое спасибо !
Make glaicial acetic acid and ethal acetate
Need to buy some more sulfuric for that 😭
Wel dont make 1.5l of H2SO4 becaus youl get arested
@@Dlab_s nah I'm not on that scale, I only have 10-20mls left lol
Ok but be careful beucause the EU regulates it and large amounts are ilegal
BRO PLEASE WEAR GLOVES. Especially with picric acid that shit stains like crazy.
Bro I wore gloves most of the time, and yeah the staining is annoying but comes out after 15days
Vynil gloves

What the fuck is wrong with your discord server; i cannot message nor chat with anyone else, it has only 3 sections (rules, announcement, and general as voice). TF men, make a text chatt channel and add some more text channels like "chemistry help", "explosives chemestry" , electrolysis chemistry etc
