More colours! We attempt two more transition metal complexes featuring the carbonate/carbonato ligand, featuring my usual enemy ammonia Paper procedure we are following: https://www.ncbi.nlm.nih.gov/pubmed/15811661 Links::: Subreddit: https://www.reddit.com/r/ExplosionsAndFire/ Twitter: https://twitter.com/Explosions_Fire Patreon: https://www.patreon.com/ExplosionsandFire Join the Discord!! https://discord.gg/VR6Fz9g Music: from Aphex Twin's soundcloud dump, track name: 11 Donkey Rhubarb Remix
"Everything feels like it was two months ago," is too real my dude. How have you managed to speak so deeply to my soul within 15 seconds of the video starting. Love you australian shed chemistry man lmao.
What's sad is that I looked it up and that video was over 5 months old... goddamn not even close!
@Extractions&Ire I'm mortally afraid of losing track of time.
Expecting blue, but getting green? Revenge of the yellow.

Nickel Hydroxide. The curse of yellow chemistry has once again infiltrated your blue chemistry.
För Sverige!
who needs to study for your degree when you can watch tom swear at unwanted green boi
unrelated: please upload a video on carbonyls in the next 9 hours it's important
Ok I'll do it, but no theoretical. Only practical examples that quickly lead to my death
@Extractions&Ire noo don't claisen condensate yourself you're so sexy aha
@Jack Mesnard I laughed more than I should have.
We desperately need some more 60s chemistry. Great Video.

3:17 A.M in Europe still not sleeping but watching some chemistry videos instead and I love it.
>3:17
I take it you're in the UK given that you're not on CEST... It's well past 4 here.
Corona virus win
Oh look he uploaded, ebic.
EDIT: holy shit my man separated crystals by hand
@Pineapple but still scarily bad.
@Extractions&Ire So you're the chemistry Loki.
@funnyyylock Like the Diogenes of chemistry. A brilliant chemist with the sensibility a unstable homeless man.
@grovermatic this !
:)
@Extractions&Ire you're following in Louis Pasteur's footsteps and he really was a chemistry god. Separating crystals by hand is how he discovered enantiomers!
I've used that kind of pump before, I thought it worked pretty well but I had a very reliable 12v power supply
The 3 prong plug for the pump is UK. We use it here in St. Lucia as well
Decent plug, but it's a bitch if you stand on one in the dark
@CAMSLAYER13 Worse than lego i'd say
@Vulpa Having stood on a broken bottle once I can assure you it isn't the worst. Know what I live in the UK, and I can honestly say that never comes up in conversation (standing on a plug in the wee hours I mean), although it seems to be become a trope on YT, especially on science channels. UK plugs seem to have become fetishised over the last few years, yay for British engineering, even if we don't make anything anymore, and are sliding in to obscurity at least we can be proud of our plugs, lol.
@diecast jam true, we actually have that conversation for the day i find around me, like leaving your iron's lead and plug hanging from the ironing board, you come in and wham stand on it or catch it with your foot in some way, its rare i think though, and turns out most people never learn to iron clothes (around me)
I have used that pump before its okay but I have had a lot more success with a product from Piab called vacuum ejectors they use compressed air to pull a vacuum the nice thing about that is you wouldn't have to worry about any thing flowing back in to the pump. Here is a link if you would like to check them out https://www.piab.com/en-US/products/vacuum-pumps/
transition metal chemistry is my shit, I wish more people covered it.
It's not just electroplating and precious metals, there are so many cool things like semiconductors and photocatalytic properties, right? :D
@TeslaFactory Exactly right!
Thank you so much. I appreciate you so much. Thank you for the time you put into these videos. I adore quality
Glad you like it mate!
I use a small 2 stage diaphragm pump similar to the one you have for anything that i dont going through my normal pump. They are nice because they are easy to open and clean.
I should spend more time on transition metal complexes, because I really like the colours. Nice video!
Why are your hydroxides so foamy? I've never had TACS foam.
I remember the first time I made tetraaminocopper. I loved it so much I spent a whole bottle of acetone precipitating it. Amazingly, it's remained stable for over a decade!
Dennis W probably because of impurities in the starting salts
Great vid and some cool chemistry as always! Love playing a game where I count the chemical safety violations in each episode (at least according to American standards, I dunno how you Aussies do things down there)
Hey Davy, I've used these pumps before in the past, they really need almost 2A at 12V to get down to a reasonable vacuum level. They don't stall once they reach their maximum vac level when supplied sufficient current
That purple is fantastic! I agree with you, tetraamine copper is so vividly purple in real life it looks unreal. Hopefully you can get that nickel to “come down” as expected... good luck
Green is just yellow disguised as blue so all green chemistry is lying
Would that make green worse than yellow?
@Steven H. Idk I would guess so because at least yellow is upfront and honest about how shit it is but green is trying to hide it all
I love complex ions, they have some of the most striking colours. I encountered some in class while following the procedures in The Semi-Micro Qualitative Analysis by C.H Sorum. Nice work mate.
Of course! It was the yellow getting into your reaction again that gave you a green precipitant when you should have had blue crystals.
I always look forward to your videos. I'm an EE major but I loved every chem class I took. Can't afford to take any courses outside my major right now, but when I can, I'll be taking some chem courses again. You keep the bunsen burner in my heart lit, my guy.
12:40 I had one of those in the lab for a short while, but found the aspirator pump is way better. If you use a aspirator pump at home, you can collect the water for the garden or to flush the toilet or something, so nothing is wasted.
EDIT: I just found out that it is called an aspirator pump, not a water stream pump
I love chemistry, i dont do chemistry. You're doing a good job making entertaining content for someone like me who just enjoys seeing and understanding how real life magic works
You really show that you dont have to have expensive storage equipment to do home chemistry it's amazing
I love your video's. I read stuff on SM on making Oleum or SO3 in the shed. It seems (HPO3)n is able to dehydrate H2SO4 into SO3, although being moderately difficult to do. There are more ways, and the chemistry itself doesn't seem to be very interessting, but i really would like you to make a video to see you fool around with the stuff and show their properties. Thanks for the cool content.
Excellent video as always, looking forward to seeing the energetics!
Loving the included source links within the video. Much appreciated.
loved that last shot of the carbonato ligand test with the HCl, the music was also paired really well
Copper dihydroxy tetra-amine complex is my favorite color/colour. I keep some I made in a jar with an LED under-light for display.
Awesome video as always. I'm wondering though, why are the solutions foaming so much ?
I think the heat decomposes the ammonium bicarbonate maybe. Small amounts of gas get caught pretty easily in the chunky solution
nothing feels better in this quarantine than observing your reactions to the smooth grooves of aphex :)
i'm thinking of doing a video which is just music and nice shots of the chemistry. Like a music clip/chem compilation, because those are my favourite bits! I get annoyed editing when my voice has to come back and explain things haha
I knew the green was going to be an issue. I bet it was blue with yellow hiding inside of it.
Use this pump for resin and silicone degassing. Works great with 20A power supply. Consumes up to 2.5A as a vacuum pump and up to 7A as a pump.
12:49 Have you considered using a recirculating water aspirator pump? They pull a better Vacuum than a little diaphragm pump like that. Nurdrage did a video on them.
10:45 It's a british plug
Used one of those pumps before to do vacuum filtering. They need to draw something silly like 3.5 amps at 12V in order to run properly without stalling.
Ha! Nice work. Love the flies, I had a similar thing happen to me. After carefully extracting and purifying a plant extract, during the final crystallisation a couple of flies got into the evaporating dish and became the major nucleation sites.
side note - i came across your videos coz I've been playing with oxalato complexes recently, and experimenting with cobalt at the moment. good results so far with iron, copper, nickel and aluminium but cobalt is a bitch. Trying to get it into the 3+ state, but it keeps turning back into the 2+ and precipitating out as pink cobalt ii oxalate. Some cool green colours but not the blue I'm aiming for.
I've been using one of those same vacuum pumps for over 2 years now. Works great and is perfect for keeping a decent vacuum going for long periods without the noise. Definitely make sure you have a solid 12V though. They will get hot and bog down otherwise. It's survived all manner of nasty crap being spewed through it. Super easy to open and clean out. the rubber flappers are really quite sturdy. And in a pinch you can even pump water with it. Doesn't pump a huge volume but does put out good pressure.
ah yes insect oxidation
Ni⁺⁺ + insect -----> Ni⁺⁺⁺ + dead insect
It was the insects fault!!! Of course. Goddamn flies. I will kill them all
@Extractions&Ire yes they are irritating
Ohhh... you reached MY favorite part of chemistry, the one that made me choose this carreer of coordination/organometallic chemistry.
Why are you PHd'ing in Physics and not Chemistry, in the first place? It is obvious you love chemistry.
I got one from Amazon for around $20 USD and used it to lower bp for distillations. Worked well & still works, but loud as f*ck. Was planning on trying it for vac filtration but haven’t gotten around to it. BTW there’s a zillion of these available online - they’re all the same so get the cheapest one. Pulls about 20 mmHg on the gauge.
dude my knowledge of chemistry is limited to the remnants of what I studied in hs so I barely get anything you do but both of your channels are interesting as fuck and one of the few things that get me through these shitty times. keep it up
great video as always sir and glad to see you well :)
Before watching the video, I’m sure all your work rewarded you with high yields of end products that were very pure and behaved exactly as you wanted them to.
Fuckin' nickel hydroxide!
Exactly!!! Now don't watch the video
For the Nickel Hexam1ne complex I've gotten decent results by putting metal nickel into a concentrated NH3 solution. Over a few days the metal broke down in the naturally alkaline NH3 and created the complex at ambient temperature.
Used those pumps often, I found the best power supply was a TATTOO 12v. You just have to cut off the foot peddle and twist the wires together. Then you have a variable pump that can pull a vac of 30" of Mercury or just a little vacuum if needed.
Pump likely needs more current, it's a fair sized motor and under stall-load probably draws a few amps. The power supply should ideally rated for over 5 amps to be on the safe side.
I've made the copper one by accident one time, not sure what I was initially going for
As I've read you need ammonia atmosphere in order to get crystals and that was nothing I could do sadly.
I use a tiny 12-16v vacuum pump to degas wine from brewing and to seal up leftovers
It fully removes all the gas from both

Not dead flies, fly shaped crystalline structures. They're art

@sam Miller no, he shouldnt! i would love, to continue watching his hillarious videos.
sam Miller - 2020-10-02
bad. It would be more fun if MeTh was part of the chemical equation doe
bad. - 2020-10-02
@sam Miller now i think of something like methylthorium? :D
sam Miller - 2020-10-02
bad. Methlamine. I think I spelt the wrong
