We prepare sodium azide by acting upon sodium amide with nitrous oxide gas. The azide is then precipitated as the sparingly soluble silver salt. Since we received numerous complains about the computer voice, we tried putting just the essential text onto the screen. Let us know what you think about this approach.
You absolutely amazing. Astounding chemistry from a fantastic chemist. Kudos and #staynerdy
Thank you!!!!
Cool set up! You make a lot of your own glass pieces?
Thanks! Yes, I'm a bit into scientific glassblowing as it is really handy if you're a chemist to just quickly make something that fits the experimental requirements. In former times (like 19 - hundreds or something) most chemists first started by learning how to work glass, as they made most of their equipment themselves.
@Astral Chemistry that's really cool... am trying to start glass bloiwng but I cant find any information on making multiple glassware like erlenmeyer flasks which have the same volume without the need of complex machinery... Its a mistery to me how glass blowers can make multiple of theses flasks with them all having the same internal desired volume....
I like the voice, it reminds me of CHEM PLAYER who you seem to have replaced!
BTW loved the voice. Much better to for the video
Thank you!
Nice job! great to see an alternative method. and great to see a new video from you - i thought you quit youtube or something.
Thank you very much! :) Well, I am just very busy with "real" chemistry right know. But I try to make a video every know and then.
Love your uniqueness, love the videos, miss the sexy voice and I would say that you should put voice and text in the video. This would be the best compromise. (Merry very late Christmas :)
Great video, as usual. Love your weird glassware setup!
(And I do like it with just text and relaxing music.)
Thanks! And thank you very much for your opinion!
Whats the song called?
我喜欢这个音乐music
got hooked at moonlight sonata :)
Please use the computer voice again. You can still add text to the video, so if people don't like the synthetic voice, they can just turn off the audio.
Great video! Moonlight sonata was a bit of a depressing choice of music, perhaps something more upbeat like a Haydn Sonata next time? ;)
We're open for suggestions. As long as we don't to put a "make your own music in the background for the video" text on the screen :D.
Astral Chemistry Mozart's rondo for violin in C major is a good happy one =p
That's a great experiment you've performed there I don't think it's been attempted on Youtube before and the indicator turning blue with the production of ammonia but I'd preferred a voice rather than text in this instance maybe you could redo one in the future and explain things blow-by-blow rather than just show them plus hold an indicator paper after adding azide to water or dilute acid signaling the presence of hydrazoic acid!
Please make a video on nitroglycerin.
Maybe you could replace your nitrous oxide-generator by (modified) cylinder containing N2O which is used for the preparation of whipped cream . The thermal decomposition of NH4NO3 can become dangerous.
Or you get it from airbags
Awesome
Thanks!
voice is what makes chemplayer chemplayer
I like the new music (Moonlight Sonata is a kickass song), but i do miss the voice. I watch these while i'm working, so the voice allows me to keep up with the video without having to always give it my full attention.
Hi You look like you new to YouTube! Can you make Chloric Acid from Sodium Hypochlorite
You can certainly prepare the chlorate first via disproportionation and then carefully acidifying that at low temperature with a diluted mineral acid.
I want to warn watchers that attempting to duplicate this video may lead to death or dismemberment. This is NOT for amateurs.
DavidFMayerPhD Two points. First, I’m watching videos of other people doing this. Two he is working under 10 grams. With those amounts, you could use a sheet of 1/2” polycarbonate as an explosive shield
Merry christmas
Merry christmas!
That stuff is a kinetic solvent and can liquify things really fast. https://www.youtube.com/watch?v=RkgOI91_mgs
So I have 1 question. if you are synthesizing sodium azide then why would you be adding silver nitrate... then you say silver azide precipitates.. go to 5:19 and. For your self
Wow nice video. forgive me if I'm wrong but doesn't sodium azide form an extremely toxic gas upon contact with acid?
Thanks! Yes, it forms hydrazoic acid. The smell is terrifying btw. We've prepared it in this video: https://www.youtube.com/watch?v=53BvufurXKA
@Astral Chemistry Oh okay haha my brain jumped to oh shit mode when I saw you add your impure sodium azide to the dilute nitric acid. It seems like you know what you were doing and were expecting it which is good haha. I really like your videos so keep it up!
Have you ever thought of making perchloric acid? Wouldn't be the first unique thing you've done
Yes, thank you.
However it is not that much better than a high concentration of caro's acid or marshalls acid, if we are talking about just throwing in organic material. Where it starts to get interesting is when we start to think about organoperchlorates like a perchloric acid ester. Chloric acid is actually the weaker oxidizing agent however it is much more reactive. But there are already plenty of videos on that one.
What song is that
Honestly I haven't seen that weigh boat reacting setup before, prrtty neat. Seems pretty limiting in terms of quantity though doesn't it?
Astral Chemistry oh geez what's the liquid ammonia method? Liquid ammonia and molten sodium sound like a bad idea haha
You're confusing the two methods. You can either pass gaseous ammonia over molten sodium at elevated temperature OR you can dissolve solid sodium into liquid ammonia at around -33 °C.
Astral Chemistry ohhh my bad. Yeah I saw nilereds video with dissolving sodium in ammonia, but I didn't realize there was a reaction taking place...
The reaction is actually really slow without the iron (III) catalyst. When you have that blue solution of sodium in ammonia, you can add Iron(III)nitrate nonahydrate (just a few mg) and the colour will fade in a matter of minutes as the sodium amide is formed.
Astral Chemistry that's really neat, I didn't know that
The music is just horrible, you are missing the point of a video vs a powerpoint or slide show. make an effort overdub with voice or give up this half hearted approach.

But I like the computer voice! It's much better than just text, people should stop complaining.
Great video!

It is not even the beeing different thing. We have always been using the TTsAPP with the Microsoft Anna voice. I think chemplayer might have switched the voice or the application.
Yes, you're right. The voice is sometimes hard to understand and the pronunciation is terrible with all the chemical terms. We're open to every software as long as it is for free and easy to operate. Any suggestions?
John C - 2017-12-26
Your channel is very unique - you are taking approaches (synthesis) that are not on any other Chemistry channel. Such as the "Acetylene to Benzene" and the "Preparing a platinum catalyst". Great Stuff. The only suggestion I have is "just text" affects the flow of your video. So a Mechanical voice with text below would be a good compromise. I believe at one point Chemplayer got the same complaints so they provided all the text in the first comment section for those viewers hard of hearing.
Astral Chemistry - 2017-12-26
That is very encouraging to hear. Thank you!
We always try to do something new. Because what's the point about recording the 10th video about making bromine? Yes, I agree. With just the text, the video did not really have a climax. So we have another video coming for tomorrow or so. We'll try again with the voice and just a little bit of text on the screen. And then we'll pin the text as comment. I guess thats the best compromise.
