http://www.sciencemadness.org/scipics/Engager/TzOTC/Synthetic%20routes%20to%20tetrazole%20compounds%20based%20on%20OTC%20materials.pdf Page 8-9 So it is kinda hard to know the actual chemistry going on in this video, you need to follow that Engager text. It's kinda like Masterchef I guess, you could never replicate their meal after watching the show but they give you the recipe and you can do what they did. Or something like that. I once tried a masterchef recipe and it ended much like my crumbed fish things did on the night I filmed this video.
I just noticed the part with the chem player text to speech voice. Lol.
if the ph Control is needed, you could use a Phosphate buffer solution for the alkaline side.
btw your hydrazinsulfate is an acidic buffer on its on, hydrazin is an weak Base, so the korresponding hydrazonium Ion is a weak acid.
so your hydrazinsulfate does not need to be impure with sulfuric acid.
That pink-ish compound looks ammonaical in nature, did you test its flammability?
video looks great with the light! and your a great chemist!
sulphuric acid in PET hahahaha
you're just so fun to listen to very nice video :)
Please explain how you figured out to use a vacuum cleaner in place of a vacuum pump.
Yess...u r right
Inst that like a pretty obvious improvised solution when you dont have a pump?
On the PUMP!
If you can't controle the temp, why don't you use a oilbad?
+Sam G The hotplate is alright, and temp control isn't like super super crucial. I could just put a bit more care in and be able to hit the temp windows perfectly
Hi! Nice video. Why don't you link the site where you found the procedure? That way it woud be much more easy to reproduce.
+DiaveD Good idea, I should be doing that, i'll link it now
Glad to help :)
Cyanamide from 9/11?

Looks like cat skat...ru poo?

P hach changes
I wouldn't had even handled the container of cyanamide with my bare hands...
Why would they dye sulphuric acid?
douro20 A bit late, but often companies will dye acids to indicate concentration. Drain cleaner acids also tend to contain organic passifying agents so that the cleaner doesn't eat away your pipes when you pour it.
Also to tell if that supply is being used to manufacture illicit drugs. Lots of pink amphetamine sulphate gets seized by police and they can figure out that the manufacturer bought x-brand sulphuric acid from the hardware store and monitor future purchases, might just be a result of the classification of concentration, but the cops definitely use that technique to catch drug manufacturers.
The fact that you're doin chem at uni and you say you're terrible at it is honestly both very inspiring and slightly depressing
In the southern United States, I can buy a litre of Sulphuric acid for about $9.95 (USD) at appr. 94.1%. This gives me about 850ish millilitres of 18M acid once it is distilled. Jealous?
I can buy azeotropic sulpuric acid on amazon here in Germany. Also Na metal and red P from chem suppliers without questions asked etc.
@T P
In germany? I heard that in germany you can get the police knocking at your door for possessing potassium permanganate. And buying red P will get you questions regardless of where you buy it.
@Pietro Tettamanti you heard wrong, Germany is actually pretty cool for hobbychem, although I don't know about potassiumpermanganate maybe there are some questions and of course you need to be over the age of 18, and have no criminal record obviously
Yeah, and I can also walk into a store and buy a ~liter bottle of 99.8% pure potassium nitrate crystals for a couple bucks, no questions asked.
It's sold as stump remover. Apparently that's rather difficult in the rest of the world...
It's also a couple feet from jars of pure powdered sulfur; that's for roses.
I get pounds of alkali metals and alkali earths at a time, up to a kilo of red phosphorus and iodine, a plethora of acids, etc. Though I know that I am being watched, which comes with the territory. Jealous?
I love your ghetto chemistry and even though I know almost nothing about chemistry I love these videos. best combination of educational and schadenfreud I've ever seen
Dude, the sound on this video is terrible... Does anyone else hear the static?
Edit: Wait... is that rain? lol. If it is then my bad. That was some hard ass rain if so.
No it's static! The camera I was using had a very small, very bad microphone. It died one day, and started making all this static. With no external mic port, there was nothing I could do! Luckily I worked out some other things to film with pretty quickly, the static didn't ruin too many videos!
@Extractions&Ire Oh ok. I heard you mention the rain in it and thought maybe it was just some particularly terrible rain.
Anyways, keep up the good work! Love your vids.
Hope you got the TLC and chromotography thing worked out for the Epazote peroxide extract analysis!
If you have enough light, use the natural light. To me it looks better, but that may be because I've developed an artificial light phobia by being inside too much. I wish I could do chemistry outside, but my reactions would literally freeze (stupid winter).
+David Allen I could have easily distilled dichloromethane today without a heat source, stupid summer. I like doing chem during the night, like this video, so that's when i'll crank out the large light but otherwise natural light it is then
@Extractions&Ire
ouch, sounds hot. I forgot that you're on the other hemisphere, kinda a weird thing to think about. And this text is just here because I can't think of something smart to write that'd make me sound cool

Even the now very famous Russian-British chemistry professor at Nottingham will admit that he's not a very good synthetic chemist. It takes quite a lot to be a good one.
