NurdRage - 2022-11-25
In this video we use a nafion membrane cell to make sodium hydroxide by electrolysis of sodium bicarbonate and separating and isolating the ions. If you electrolyze water you generate hydroxide ions at the cathode, and hydronium ions at the anode. If you could some how split sodium bicarbonate, then mix the sodium ions with the hydroxide ions, you could make sodium hydroxide. Of course "just" splitting ions completely glosses over the nuances and complexities of chemistry. But interestingly enough, a cationic exchange membrane like nafion essentially allows us to that by allowing cations to transfer through, but blocks anions. To do this, all we do is get the nafion divided membrane cell we built in a previous video and insert it into a larger container of water and sodium bicarbonate. Using a titanium cathode and a cobalt oxide anode (although you can use nickel, platinum, or carbon), we make the sodium bicarbaonte solution the anolyte and use deionized water as the catholyte. Applying an electric current we separate the ions in sodium bicarbonate and pass the sodium through the membrane into the cathode side where they meet up with the hydroxide produced and create sodium hydroxide.

Glad to see you're still at it. You were the first chemistry YouTuber I ever watched and you started off one hell of an addiction.
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.
OH MY GOD YOU ARE BACK 🤗🤗🤗
I'm not a chemist, and love your videos. Thank you 💖
Great to see you get some videos out again. never miss one. keep up the great work.
Glad to see you back after so long
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!
or ionomer cement which is deionizer resin mixed with cement and casted and this works just like nafion.
What voltage do you use?
@@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.
Wow two videos in a week. Glad to see more content from you again!
wait I missed one?? :O
Another brilliant Nurdrage original video. So glad to see that you're still producing even if it's just working with vintage footage :-) I've been binge watching the sodium production and water purification videos again and again to tide me over, I'm going through a tough time myself, I know I'll never be a chemist or anything close to your level but when I watch and listen to Nurdrage I can briefly feel smarter than I probably am, there's something oddly comforting in there. Thanks from a loyal fan.
2 videos in a week. A blessing indeed 😌
I am very glad you are back, I always find your videos engaging.
So glad to see you back NurdRage! Lots of good vibes!
I actual play around with the idea of creating a diy exchange membrane from water softening beads a while ago.
Do it! It would be epic if you could make your own PEM for fuel cells
I have a video on that called ionomer cement where you put them in a blender and mix them with cement powder.
I'm jazzed that you're back after the nearly year-long hiatus. I love these videos
The Return of the King! Good to see you back!
so happy to see you back
2 videos in 2 days
you're spoiling us
Awesome new video; soon as I saw it, I pressed play. Fascinating as always.
I remember the good old days back in high school when I "borrowed" chemicals and equipment from chem class so I could go replicate NurdRage experiments in a shack in the backyard. I remember being elated to synthesize nitric acid with sodium nitrate, copper and hydrochloric acid. I did it for my love of chemistry. Thanks for another good video and hope to see more! Keep it up.
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 .
It was an excellent video, an excellent technical explanation, your video was liked here in Brazil
I follow your channel from the early start. Nice to hear from you again.
It's great that you're back!!
You have no idea how happy I am to see that you're back.
Great to see a new video! That's one insane membrane!
This is one my favorite channel I learn a lot from this, thanks for sharing nice idea on how making sodium hydroxide love it..
So glad to see your videos again! 😁
Welcome back! Hope to see more videos soon
2 videos in the span of a couple days!? we have been blessed
Hello again! I feel completely stupid when watching these videos but can't stop, science is so fascinating.
This will certainly be useful for my RV lab.
I love your content. It seems scientific like yours on YouTube is getting less frequent... I'm so glad you're back and I hope you're doing well!
love seeing uploads from you
Lovely always glad to see a nurdrage video
I've been wanting to do this for a long while. Thank you
Hello. Nice to see you again. I was waiting for your videos. Plz keep uploading more videos. We love your contents
Another really good video; keep 'em coming.
Glad you're back nurdRage. Thank you :)
Thanks; I am trying to think of more exotic compounds that could be made, but maybe that's on your list. Cheers, Mark
Great video! Thanks to you I have bought small piece of Nafion. I can get NaOH easily but the process here is so interesting that I just had to buy the Nafion to see and expolore the process. All my years with chemistry both at university and job now and I never heard of Nafion (well we had some little info about membranes in general but not this black magic, dark arts thingy called Nafion) before you have presented it to me. Thank you so much for this video!
Return of the King
Wow! 2 videos in like 3 days. Nice.
Excellent work.
Crazy if you had this great video sitting on a harddrive for ten years.
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.
Always appreciated.
The Nurd is back in town! Cool!
HE’S BACK BABY
Yesss, a new Nurdrage video :)
Very cool video, your last statement made me laugh "I can't get sodium hydroxide but I can get Nafion"
@NurdRage - 2022-11-25
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.
@warmonger12z - 2022-11-25
That's a very generous donation - where did it come from?
@cake4919 - 2022-11-25
@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 https://youtu.be/zbVm4NFrWJM
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.

@fireveno - 2022-11-25
Can nafion work for multivalent atoms like aluminum? Can this whole experiment be done in a way to drive aluminum atoms to a electrode?
@OldShatterham - 2022-11-25
I would definitely look forward to that!
