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
@@vulpa8226 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.
@@yakacm 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 think some yellow got into your blue and made it green, m8
Of course! Goddarn yellow!!
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

Yellow has once again infiltrated the superior blue chemistry to make a bastard green child
Green is just yellow disguised as blue so all green chemistry is lying
Would that make green worse than yellow?
@@wafflenovas 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

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!
“Unknown concentration but reasonable strength” 🤣
I've used that kind of pump before, I thought it worked pretty well but I had a very reliable 12v power supply
“Everything feels like it was two months ago.” True that dude
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
FYI if that motor stalls out for long (more than a couple dozen seconds at a time, or less I'd bet) it could burn out. Motors draw more current the slower they run and afaik cheap dc motors like that are really not designed to pull max current for long at all, it gets really hot.
This might not be a problem at all if that power supply has a low max current draw. If that's the case then there's no harm in stalling.
I think the power supply has a low current draw yeah. Will replace it with a 2A one as advised by others, to prevent it stalling
"Solution of unknown concentration but reasonable strength" is one banger band name
More like a Culture ship. I think there is one named Limiting Reagent or Limiting Reactant.
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.
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!
HINT: If you put your conc. ammonia in the freezer beforehand, makes it a little nicer to work with pouring it out of the bottle because the vapour pressure at such low temperature is very small (you don't get that terrible out-gassing as you crack the lid open!)
Your videos get me through this quarantine
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.
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.
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.
Beginners guide to qualitative chemistry:
Add some volume of reagent 1 followed by a bit of reagent 2. You'll know when sufficient reagent 2 is added when it's enough. Exact concentrations aren't critical. This is the chemistry equivalent of pi=3=e
I love this channel
I should spend more time on transition metal complexes, because I really like the colours. Nice video!
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
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
3:35 The nickel nitrate's stir bar wiggling oddly amused me
Hey about the small diaphragm pump, I have use those for vacuum filtration for a fair while
the adapter you are using looks like a charger adapter, probably not the best choice
if you could find a 12v 2A adapter say from old routers it would run continuously and wouldn't stall
ebay is MIA because of Covid, but a PWM controller would make things even more controlled (10A ~$6aud)
The diaphragm is made of silicon so are the valves so the thing is pretty resistant to most chemicals, in my case what finally killed one of mine was vacuuming toluene for long periods. it permeates through the silicon and dissolves the PVC parts behind. the body is glass reinforced nylon so I don't think it would like HCL and a Cr6
These pumps are also fairly tolerant of liquids, you can pump liquids or gas/liquid mix, just need to reduce power a bit
One other tip, I had 2 of these so I could use them in parallel for doubling the flow or in series for increasing the pressure or vacuum (won't quite double the pressure, more like 1.5 times, still not bad at all considering)
in future, you should take pictures of crazy colors that don't "come through" on camera with a phone camera or DSLR if youve got one. colors tend to be easier to pick out in photos than in video, especially if you want to edit things. I do photo retouching, if you don't feel like it, I'd be totally down to work on some beautiful chemistry colors!
loved that last shot of the carbonato ligand test with the HCl, the music was also paired really well
I don't even know why I watch these, to be completely honest. I know jack shit about chemistry!
And yet you make it look so interesting...
I did it, I am here, 108 videos on this channel and the 19 from the main channel, best week and a half I have had in a while watching this janky but brilliant content, from legit chem to random cooking streams to random 144p glassware unboxing, I can't wait for more man, keep up the good work'
Woah, yeah it is a bit of content these days... Looking forward to making more!
No matter the problems or the solutions I like your vids man.
Always a good day when one of your videos appears in my feed mate.
At least it didn't turn yellow Lol. Great video!!! Keep it up!!!
It's always a plus! Thanks!
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.
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 www.piab.com/en-US/products/vacuum-pumps/
Of course! It was the yellow getting into your reaction again that gave you a green precipitant when you should have had blue crystals.
Excellent video as always, looking forward to seeing the energetics!
Nice! I do love colorful chem.
Loving the included source links within the video. Much appreciated.
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.
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.
It’s a gorgeous color and the nitrate and perchlorate complexes are mighty useful too.
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.
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
great video as always sir and glad to see you well :)
You really show that you dont have to have expensive storage equipment to do home chemistry it's amazing
I knew the green was going to be an issue. I bet it was blue with *yellow* hiding inside of it.
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.
Thank you for the nice pigment footage!
E&I "hand-wavy" chemistry for half a decade. :)
Very satisfying colours👌
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)
For what it's worth, that's a UK plug on the pump at 10:45-ish, one benefit of which being that it most likely has an internal fuse in the plug head itself
Cool video and love the colors.
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
Tom: the nickel, well, there's nothing in there.
5 flies: are we a joke to you?
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
13:56 the extra weight is the weight of your sins from killing those flies
I like how casual you are. And every time u mention the sixties i laugh my ass off.
Love the content my mans
It's the same little pump they use for your portable tire inflator... Just plugged in the pull-side... It's a Reed valve on an oil free piston (please give it a drop of oil it helps immensely)
They have their uses...
Finallyyyy I recognised something. That plug with the adaptor is British.
Holy shit, 3 videos in one month, the one upside of lockdown
Yeah I know, I haven't made this much content in a while
@@ExtractionsAndIre You're on a roll man, keep it up 👍. This pleases the A L G O R I T H M.
The plug for your big pump looks like a U.S. 240v plug. Commonly used for appliances like stoves, refrigerators, washers, and dryers. It's also not uncommon to see it on tools with large motors on them like mills, lathes, and CNC machines.
The plug is a US 220v plug. You see them a lot on washers or dryers for laundry units here.
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
You should write a paper about your novel penta-fly nickel carbonato complex! I feel like I know handful of words in a foreign language, and just throw them out randomly hoping they make a sentence.
Loving the Aphex Twin :)
Only the one who goes through all step in experiment, washing those dirty af glass, etc, know your effort in making this video. Respect ! (I almost died when trying to seperate [Cu(NH3)4](OH)2 crystal from the batch, its beautiful blue color of Cu(OH)2 after my seperation kills me :(( . Where is my lovely deep blue complex ????
Those pumps tend to draw a fair bit of current once you put a heavy enough load on them. Pulling a strong vacuum to suck something through the filter does just that and I suspect your power supply simply isn't up for the task. As the vacuum builds so does the current, eventually the supply can't keep up and the voltage tumbles until the motor stalls out.
You want something that can deliver at least 3, better 5 Amps at around 9-12 Volts. An old computer power supply would work well, or maybe a cordless drill battery or in a pinch even a car battery charger if it has a 6V setting.
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
The adapter you didn't know was a British one - very safe for everything but feet.
I've also used that type of pump, you don't want to let it stall for any time since it will slowly overheat. That AC adapter is awful, try finding an actual 12V supply at several amps so it never stalls.
Anyway, the pumps are surprisingly powerful and can really develop some serious pressure, on the order of around one bar. Pretty decent for a small plastic pump. The ones I got were pulled from a blood pressure cuff machine, hence the need for high pressure and moderate flow rate.
You can get an aquarium air pump for 5-10 bucks and hook a hose to the air intake for vacuum filtration. Your motor most likely needs 12v by the way so check the adapter you hooked to it and also look at the ebay listing it may list the max Amperage. If not get a cheap speed controller from Aliexpress for 3-4 bucks and then you can adjust the pumping speed.
Motors typically take quite a bit of current. Especially ones under as much load as you are putting that one under. The little phone charger power supply is definitely the problem. Once vacuum gets low enough, the charger is hitting it's current limit and shutting itself off so it doesn't explode and/or catch fire ;)
Find something that has a rating for current on it. You probably want something around 1A or maybe a bit more. That charger probably does 100-500mA. Love the videos!
Great advice thankyou!! Will do that!
Always make me smile
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.
I made a filter pump using something just like this. I used a mason jar and some tubes and hot glue to act as a trap for nasty stuff. I charge it with bicarbonate solution for acid gasses, ice water for volatiles, etc. Might be an idea for your little pump.
I have been using this kind of pump for years. They are quite reliable with the right power supply.
Got mine from ebay as well only they were much cheaper and came with a psu
I think NurdRage mentioned a cool way to make an aspirator based pump for vacuum filtering a while back in his lab equipment series. Basically just an aspirator adapter and a high power water pump he got cheap online running in a loop.
Hi. Ni(III) is very rare - I personaly made only NiO(OH) (which is mixed with NiO2) by oxidizing Ni(OH)2 by persulfate. Nickel, unlike cobalt, doesn't form easily complexes in III oxidation state. So you have all the time [Ni(NH3)6]2+ in the beaker, which decomposed in to nickel hydroxide.
Copper hydroxide contamination in your tetraaminnecopper carbonate is due to loss of ammonia on the air. These ammonia complexes slowly lose their ammonia, which is replaced by water. They must be store under ammonia atmosphere in closed container (I have for years [Cu(NH3)4]SO4.H2O in the jar without loss of ammonia - I added two drops of 25% ammonia to the jar to make protective atmosphere).
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.
I always come for the music
I love transition metal coordination chemistry
His Beakers are like the Bermuda Triangle for bug of all sort. Looks like he has to bug fix his beaker again XD
The adapter was a u.s. 220 plug. For wash machines or dryers. Some fridges. Etc
I'm looking for a No Trespassing sign for the lab/garage. I've got "No Trespassing - Trespassers will be oxidized" - - Any better ideas?
That three-pinned plug is the child of fine British engineering!
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.
