I currently intend to make a lab equipment video. I recently got a donation of expensive lab equipment (rotovap, vacuum aspirator, water chiller) and i'd like to show them since amateurs rarely get to see or use such equipment.
@NurdRage That would be awesome! Btw, about the amateur-accessible anion exchange membrane that you briefly discussed wanting to make in your video, someone has already made a video on making these, multiple videos in fact, with various different membranes displayed. His channel name is mysteriousbhoice and the channel is pretty obscure but he probably has the best electrochemistry channel on youtube. Here is a recent video of him making an anion exchange membrane, and I highly recommend checking out many of his other videos ruclips.net/video/zbVm4NFrWJM/видео.html Also, if you ever do get a large enough collection of analytical equipment it would make for an interesting lab equipment video to explain and display analytical equipment such as NMR, spectrophotometer, UV-VIS, FT-IR, etc.
bipolar electrodialysis allows the production of both acid and base, but it is quite a complex process, would be awesome to see someone outside of a fancy comercial/university lab achieve this. Maybe as a next step after finding a anion exchange membrane?
damn I wish but sadly nope however you can synthesize other membranes such as functionalized crosslinked PVA membranes which although arent as chemically resistant is good for proof of concept and small experiments to explore the science. Ionomer cement however is something an amateur can make and has the ability to be as good as nafion because its basically nafion dust from de ionization resin cation or anion take your pic and then mixed with white cement and casted as a dam which then allows specific ions to pass through. Nurdrage has an earlier video showing where u can get deionizer resin and you just have to put that in a blender.
@@CatboyChemicalSociety I was thinking the same, but just another question... From GooglePatents: "One type of cation exchange membrane which has been proposed and developed is a copolymer of a sulfonated perfluorovinyl ether with tetrafluoroethylene which is marketed by E. I. duPont de Nemours and Co. under the trademark "Nafion"." Is this correct? The TFE is easy* , but I would try the synthesis of sulfonated perfluorovinyl. Nothing like the smell of Fluor in the morning... Even easy is making a small piece. All the machinery would be "small". *Anyone can buy here.
There's this video of someone making a alkali membrane (cationic exchange membrane) to be used in place of nation membranes. The chemicals used are fairly common except glutaraldehyde, which is sold as matricide. link:ruclips.net/video/BT3HjyziH_0/видео.html
I have a video on this too but it uses Citric acid as a crosslinker instead of glutaraldehyde and the free carboxylic acid allows for cation transfer across the polymer.
Ditto... iodine tincture to I2. Back when i was a bit naughty 20yr ago. Now I'm downright evil and wanna know what happens when you throw phenyalanine in that thing.
As always enlightening video! If you can't get nafion, a clay pot works as well for making acids or bases. Make sure it's not glazed, and plug the hole at the bottom if there is one. I've gotten up to 4.5M NaOH from baking soda and 1M sulfuric acid from Epsom salt. The anion/cation you want to separate from the salt will diffuse back a bit, but the solution will be still pure because (HCO3)- is repelled from the cathode and Mg2+ is repelled from the anode. Harry from Scrap Science has more on that!
@@francisjahera1150 For better yield, It's the current that matters more. I set mine power supply to constnat 3-4 amps, and with my electrode sizes and pot geometry, was about 4-5V for the lye and 6-9V for sulfuric acid. So basically, 5V should be fine. Crank it up if it's too slow for your liking, turn it down if your electrodes start to degrade.
I recall you did a video a while back where you separated the components of a spent DI-Water producing Ion exchange cartridge fairly easily by exploiting density differences in the anion and cationic exchange functionalized styrene polymers. Have you considers dissolving the separated beads and casting a film from those solutions to use as anionic / cationic exchange membranes? Obviously those materials lack the superacid functionality of Nafion and would not perform as well but they would be more amateur accessible.
My thoughts exactly. I played around with the idea but never attempted it. The beads are cheap and readily available in bulk from places like Home Depot for recharging large whole home filters. There are papers describing the process of making these membranes from scratch but I believe using the styrene beads eliminates multiple steps. All that should necessary is to dissolve the beads in something like acetone, coating a glass plate and allowing the acetone to evaporate. (I'm going off memory here and it has been a while but I believe acetone is the solvent).
Because linear polystyrene sulfonate is soluble, they use polystyrene/divinylbenzene copolymer as backbone of resin, making it harder to dissolve. So maybe you can't just dissolve it and make membrane out of resin, and the process might also require some heat.
@@성이름-d4o4o I thought it was just sulfonated polystyrene. I really don't remember the process. I'll have to find the link to the paper. The attempt was to show polystyrene could be recycled into membranes. I think it would be a popular video if someone could show "amateurs" can accomplish making reasonably efficient ion exchange membranes.
@@hubrisnaut Maybe it's just polystyrene sulfonate, not fully sulfonated. Or is it insoluble enough with some kind of treatment? I don't know exactly though. I've never thought it could be stable without crosslinking!
@@hubrisnaut I found paper about partial sulfonation process. Is it what you've mentioned? DOI: 10.1016/S0376-7388(99)00258-6 10.1007/s10924-006-0018-3
Great video ! A question @7:18 - if you do this electrolysis with table salt NaCl why doesn´t it produce HCl at the anode to a lower extent, next to the O2 and H3O+ and Cl2 (Cl- and H3O+)?
@@NurdRage so there's a way to make HCl and NaOH at the same time by using table salt and sodium bicarbonate?(assuming both sides somehow aren't able to combine back into salt and water, ofc) Or would it inevitably be a way to turn sodium bicarbonate into table salt and make a lot of chlorine, but with extra steps? (Ik my questions are pretty stupid, but what if you took them seriously anyway just as an exercise in basic chemistry logic to explain me what side reactions are instead of actually treating me like a clueless kid(wish I had that as an available excuse, but I'm just clueless) that's just curious about what happens when you mix every chemical In sight and zap it with electricity? Like, just for fun? Lol)
Actuallllly, i had heard of a similar method of usimg a ceramic membrane, as ghetto as a flower pot for making nitric acid with eletrolysis. If your membrane is flouridated, then it should do just fine in that experimemt as well, thouse the silicone or epoxy used to seal it might not hold up for long.
Very cool and useful . Of course most people in the us can get it OTC with little hassle , but , others may not be so fortunate . There is always metathesis by reacting calcium hydroxide with sodium carbonate . Calcium hydroxide is easy to make if you have fire , limestone , steel vessels and patience . So that would make an interesting video going from driveway gravel and washing powder , to sodium hydroxide .
This has me thinking about alternative ways to perform direct air capture of carbon dioxide. Atmospheric CO2 reacts directly with aqueous hydroxide ions to form (bi)carbonate. This electrolytic way of regenerating the NaOH, releasing CO2 in the process, could be a cyclic way to capture CO2. The challenge of course is that O2 is also produced at the anode alongside CO2, so a separation step is necessary. I'd appreciate hearing your thoughts on this! What do you think about the feasibility of electrolytic DAC as apposed to the calcium caustic looping the most DAC methods use today?
I have been working on an idea to run an outboard on hydrogen sourced from sea water through electrolysis powered by a solar and battery. The issue I have is dealing with the chlorine, this set up seems to make it easier. Would you happen to have any suggestions or input into this idea? Thanks! P.s. I know the efficiency isn't going to be the greatest, but that's what iteration is for!
there has been recent advances in seawater hydrogen. Rather than a membrane, they use special electrodes that promote oxygen generation rather than chlorine generation. So type "seawater hydrogen" in google and you can find the papers that detail it.
Great work. Easy to understand. I am a researcher and I am interested in treating brackish water through an Electrodialysis system. But I don't know if I can make ion exchange membranes (Cation and anion) myself right there in the lab? Do you have any idea how can I do that? Dr. Zafar
The over-unity wackos might see this video and say HHO! HHO! Free infinite energy! Just hook the electrodes together with a light bulb! I sell plans online!
@NurdRage Anion exchange membranes (AEMs) are not too hard to make yourself. All you need is a UV light, thin HDPE/LDPE and Trimethylamine (TMA, try to get it in a Cl/Br form). Using the UV light to radicalise the polymer in a bath of TMA will make a simple AEM (frankly, grafted TMA-HDPE/LDPE are some of the best AEMs you can make). If you need papers to work from Newcastle University in the UK has quite a few papers. If you want to buy AEMs Fuelcellstore would be your best case
I made some time ago sodium hydroxide with the elctrolysis of sodium chloride. As a membrane I used a clay pot and as electrodes I used carbon rods from 6volt carbon zinc batteries for the anode and just some random copper wire for the cathode. It worked, but it took 20 HOURS TO GET 7 GRAMS. Do yeah it wasnt really efficient or a good way to make it. Also I used a variable 300w power supply as my power supply. I limited the current to about 8amps when it got that high.
"Of all the black arts chemistry is the blackest" Thanks, I never knew baking soda could be used rather than salt. I thought you could pull CO2 out of Carbonic acid under a vacuum.
Sodium and potassium tetraborate both have a 9ish pH. I wonder if you can get boric acid to precipitate in the anolyte and I wonder if reaction will go to 100%
i'm well versed in chemistry but the lil chem kid i was bounces in joy seeing the concentrated sodium hydroxide solution defy osmosis and gravity and just pump itself up into the collection vessel. Its magic seeing that, i love it. Lime, Ca(OH)2, is a dirt cheap construction material. You can turn salt into sodium hydroxide and chlorinated lime, CaCl(OCl), two essential deep-cleaning compounds, one capable to create soap, the other a desinfectant, this is very powerful technology for for instance a field hospital in rural Africa equipped with solar panels.
So I've been batting around the idea of making a carbon dioxide scrubber for my bedroom. I can't go to a space station, but maybe I can live like one. 😁 So I'm thinking that maybe I can diffuse calcium ions the same way you're diffusing sodium ions. I can use calcium carbonate as my base chemistry and pipe the CO2 from the decomposition out my window. Then I just have peristaltic pumps periodically drain my product back into an absorption chamber and then back into the reclaimer. Crazy idea?
hi @NurdRage, have you thought about designing a "salt separator" which makes NaOH on one side and HCl on the other side? maybe pass the H and Cl through a quartz tube with a UV LED shining through it so the small amounts of gas (on-demand, or as it's produced in real-time so there's no buildup danger) combine in water vapor and precipitate as an acid? the idea of a contraption that electrically produces high PH on one side and low PH on the other side seems it could be useful
How temperature stable is that stuff? Can it be exposed to sodium directly? I guess you couldn't use water, but could this be used to directly electrolyse sodium using methanol in oil? Basically, could do your magnesium process but using electrolysis rather than magnesium?
Awesome - Very glad to see you back in Action ! Nafion looks like an extremely useful product. How does it tolerate organic solvents ? - i'll investigate this time instead of just asking dumb questions.
I've tried this type of electrolysis(but using clay pot as membrane) and made some H2SO4 from Na2SO4 solution. I'm really glad to see you do such type of experiments! Awsome vid as always! ❤️❤️❤️
@@xxxm981 I saw some spots on the pot so it does corrode the pot a little. But still, is VERY SLOW. You can try shitload of times before you will finally destroy your pot. For more info, go to the channel "Scrap Science".
@@xxxm981 Sadly, no. At that time I couldn't coz I didn't have the required instruments to measure the yield. But I was able to test and confirm that it was H2SO4. Like CO2 was released when it was mixed with Sodium carbonate and produced Barium Sulfate precipitate when mixed with soluble barium salts. It contained a very minimal amount of Na+ ions that somehow leaked but was too low to interfere in any reaction.
I always enjoy your videos. I took a chemistry in highschool to see chemistry like this. The highschool class turned out to be a math class in disguise.
What if we start from sodium carbonate Na2CO3(aq)? Would the process in this video give us NaOH on one side of the membrane and H2C03 on the other side (with the consumption of one more H+)?
is there something we could use inside the sodium capture side that would avoid the hydroxide thus making a sodium metal plating process for pure sodium? While I am sure at some point I may need sodium metal so being able to make it would be good but I am really interested in purifying caesium (cesium) to use in a test of possible geological explanation for why we have so much Oxygen, constantly or consistently, as I have been wondering since plants release the CO2 by being broken down when they die, how we have the excess oxygen, and stumbled on a possible room temp autocatalystic process for cracking water of its hydrogen and oxygen that I think may be made naturally in the crust of the earth in far less pure form than what I intend to try, all based on the same concept that sunlight is able to power catalytic breaking of water using Graphitic-Carbon-Nitride. (GCN) it just has to have both the hole and electron donor in the matrix in the right quantities and configuration.
nope it will make Cl2 gas but you then need to add a UVC light or spark plug to then react it with the H2 and produce HCl. I got a video on that exact setup albeit its dated and im never gonna rebuild that again for reasons.

It was an excellent video, an excellent technical explanation, your video was liked here in Brazil
I assume this footage is also from about a decade ago given the old logo?
Is it possible to make a deionised water using both types of such membranes?
Remember you promised to make a video about anionic membranes around 2396, so better start preparing!

Awesome - Very glad to see you back in Action !
Nafion looks like an extremely useful product.
How does it tolerate organic solvents ? - i'll investigate this time instead of just asking dumb questions.
Tolerates aprotic polar solvents well, and solvents like DMSO and DMF are commonly used.
to make acids i have seen terracotta pots used as a semi permeable membrane would that not work for sulphuric acid ?
Great to see a new video! That's one insane membrane!

Cum back to RUclips it's soooo dull without you!!!
What if we start from sodium carbonate Na2CO3(aq)?
Would the process in this video give us NaOH on one side of the membrane and H2C03 on the other side (with the consumption of one more H+)?
Yep
video upplode rate increse by 10000%
what exchange payments, for what, why
ANOTHER VIDEO! WHAT IS HAPPENING?!?
This is one my favorite channel I learn a lot from this, thanks for sharing nice idea on how making sodium hydroxide love it..
Make potassium chlorate with this set-up to see how it goes
2396. Okay, see you then!
Wow! 2 videos in like 3 days. Nice.
2 videos in 2 days
you're spoiling us
Super! Thank you very much!
Every day Nurd Rage? Yes pleased!
is there something we could use inside the sodium capture side that would avoid the hydroxide thus making a sodium metal plating process for pure sodium? While I am sure at some point I may need sodium metal so being able to make it would be good but I am really interested in purifying caesium (cesium) to use in a test of possible geological explanation for why we have so much Oxygen, constantly or consistently, as I have been wondering since plants release the CO2 by being broken down when they die, how we have the excess oxygen, and stumbled on a possible room temp autocatalystic process for cracking water of its hydrogen and oxygen that I think may be made naturally in the crust of the earth in far less pure form than what I intend to try, all based on the same concept that sunlight is able to power catalytic breaking of water using Graphitic-Carbon-Nitride. (GCN) it just has to have both the hole and electron donor in the matrix in the right quantities and configuration.
Beautifull.
Can You make ammonia solution by this method? For example from ammonium sulphate or carbonate?
yes you can
What about the membranes from a reverse osmosis cartridge? What would they be useful for in electrochemistry?
they will only let water through so nope.
Can I use this setup with NaCl to make HCl? (might get banned here anyday)
nope it will make Cl2 gas but you then need to add a UVC light or spark plug to then react it with the H2 and produce HCl.
I got a video on that exact setup albeit its dated and im never gonna rebuild that again for reasons.
Who is watching in 2396?
Return of the King
Always appreciated.
4:10 When you calculate current density, are you including both the anode and the cathode, or just the cathode?
You just need the overlapping area between them. So whichever is smaller will do
