Make a Nafion Divided Membrane Cell for Electrolysis
ฝัง

- In this video we make a two compartment electrolysis cell divided with a Nafion membrane.
Ever wish you could filter just one ion? Nafion is an ionic polymer or "ionomer" that has sulfonate functional groups as part of it's PTFE structure. These sulfonate groups make the nafion permeable to cations, very similar to cationic ion exchange resin. Cations can hop from sulfonate group to sulfonate group and transfer through the membrane. Anions are blocked.
So if we apply an electric field we can force cations through the membrane and separate them from anions.
In this video we make a single compartment membrane cell that we'll use in a future video to make sodium hydroxide from sodium bicarbonate.

My video posting rate will continue to be extremely erratic. But i hope to continue nonetheless.
Thanks for still being there.
Nice to see you back. Hope to continue seeing you in the future.
Always happy to be here!
good to se your stil making video's.. how is it going with you? hope everything is ok.. i know your worked on getting a job.
Hi, we do miss your videos, but are very grateful for the time you can share with us. I hope that the reasons for you being busy are good ones.
Any and all uploads are greatly appreciated.
With a mercury cathode cell metal ions are able to pass through the mercury but the non metal cannot. This does something similar but no toxic heavy metal. Awesome!
When Cody's in the comments you know it's a good video !
Can you use a lithium battery cell separator or the ions are incorrect size?
Mercury isn't toxic. You can put it in your mouth and splash around in a pool full of it with no permanent brain damage.
@@NicolasBana yea you are right
please update mercury chatode for separating palladium with non metals contaminant Cody's
You know you miss this guy when just his intro phrase brings a smile to your face!
Oof.
"Greetings fellow nurds"
I miss the 'WARNING!' intro (the disclaimer). When you heard that, you could be assured that chemistry involving some interesting chemicals would feature in the video.
I was like MUST WATCH NOW
How true!
I wrote about this TH-cam channel as a motivation source for going into chemistry when applying to university. I'm now a second-year chemistry student at Oxford University. Thank you so much NurdRage 🙏🏼
Damn son!
I never got into uni
Maths isnt my strong point and well, you tend to need it
I also attributed my interest and choice of study being chemistry to NurdRage!
@@BackMacSci
Shout out to Julius sumner miller
Physics
Same, now I'm first year in my university.
What an absolute king
Missed your videos! Glad to see you're okay!
It is 2022 and NurdRage still lives
I remember subbing when I was 16, I'm reaching 29, holy hell it's been quite the ride
had a failed synthesis earlier today using up all of my reagents and this is really improving my mood! nurdrage videos are the best!
@@cvspvr lies, he was actually drawing grimace on all of his glassware
This youtube channel was part of the reason that I studied physical Chemistry and now work as a lead Chemist in a private aerospace company. Thanks NurdRage for sticking around, good to see that you are still posting.
The return of the king! Probably some of the first chemistry videos I ever watched on the internet, and while I don't actively work in a chemistry-related field now, this channel played a major part in fostering my passion for science in general. Always happy to see a new NurdRage video.
This footage may be 10 years old, but it's not the oldest I've seen. Been loving your channel for 13 years.
We missed you man!!🥺
A day with a NurdRage video is always a good day. :)
Holy cow he's back.
Finally some NurdRage
Welcome back! Always delightful to see a video from you, no matter how much time between. Thank you for bringing science to TH-cam, as always.
Glad to see you're alright. Thanks for the upload!
A lack of videos like your has had me feeling sad lately. I missed your videos. They are a breath of fresh air in this current climate that lacks quality of videos like your videos. Please make more!
Really missed your Videos. Me and my coworkers remade your Natrium Video in our Training, because our teacher liked the journey so much.
Holy shit !!! Youre alive !!! I missed you !
Please make a Oleum synthesis video ... i just spent a small fortune on it and am dying for an efficient way to make it .
Great to see you back!!
Dont ever leave us again we need you!
I missed you so much
Truly wonderful to see another video from you. I hope the future brings you more chances to do what you love and share it with us! Thanks for all the videos, past, present, and future! :)
Wow!! Welcome back fellow nurd!!
Good to see you back from the void. Hopefully you get to perform the reaction you mentioned now that you've shown us the archived footage
I am extremely happy that you are back to posting! You are the reason I got into chemistry so long ago. hope all is well!
Just in time to watch it with my tea. Glad to see uploads again!
Started watching your videos when I was on the first year of my undergrad course in chem, 6 years later and an almost masters done, your videos still make me click right away. Kudos!
Very happy to see another post from you ☺️
I’ve always loved your work.
Nurd! Great to hear you again!
Love to see this channel still being semi active! Miss these videos!
Nurd Rage,
Glad to see that you are still around…look forward to seeing what comes next
WELCOME BACK! Its been a while but good to see you back :)
I saw uploaded 23 minutes ago and thought “oh man I’ve got to update my phone, the date and time is screwy!”
I was so excited to see it wasn’t a mistake! Great to have you back!
So glad to hear you are alive!
NurdRage videos are always great
So many reactions I tried from this channel. Glad he's back
Thanks for making a video of a "hands-on" experience with Nafion. If you read about Nafion, it's this kind of super expensive, super fragile thing and this video helps making it more approachable.
You're always welcomed back King. Looking forward to the next upload
Good to see you're still around and hopefully doing well!
Super stoked to see a new NurdRage video!
So good to see a new production.
Great to see you back!
Bought time, I've been waiting for this video on...whatever you're making.
I'm here for the air sponsorship.
Good to see you back Dr.
Very happy to see a new NR video.
It's good to have you back.
Nice to see you back!
I am glad to see you back
Welcome Back :) this video just sparked a few great ideas thanks NurdRage.
I loved watching your videos growing up as a kid, now as a 19 year old perusing a 3rd class power engineering ticket i still love your videos and it brings a smile to my face any day I see a new post from you. I truly hope you post more soon. Thanks for posting again
Glad you are back
I remember stumbling upon your channel while I was in secondary school and getting fascinated with the amateur approach. And then I was there when you perfected the amateur production of metallic sodium with tea tree oil. Keep on trucking, good sir.
So happy to have you back
Woah! Good to see you back.
nurd rage I love you please never stop uploading.
Happy to see another video!
I'm so glad that you're fine and back
Electrosynthesis, nearly forgotten topic...
By the way, it's nice to see your uploads again.
Glad to see that your back my dude
welcome back! its been ages, I love your videos, my daughter wants be a chemist because of watching your videos with me.
Nice you are back!
Oh my god welcome back, Chem Master! ❤️ your works. Also Electrochemistry is my most favourite part of chemistry
Whoa a NurdRage video. Heck yeah!
welcome back hope you can keep posting
Hell yeah!!! Nice to see u again!
Good to see you back from the void. Hopefully we'll see more soon.
Hearing that intro chime gave me a serious wave of nostalgia...
holycrap you're back!
missed this channel so much, im still re-watching old videos
Ayyy! Nice to see you post again!
I am just glad, he's back.
nice to hear from you again. Thanks for still being here.
thank you for posting
glad I still followed you after all this time.
Happy to see
This legend is still making videos for us
You're alive!! Welcome back
Yay! you're back! Hands down my favorite chem channel on youtube.
this is the first time i really fell that i understand nafion membranes mechanics! thank you!
You're back! We missed you.
Welcome back, Dr.
Glad you are back , even if it is partly old content .
hell yeah, welcome back king!!!
"using it in the NEXT vid" WOO always good to hear there will be more, love your vids
Just the fact that this guy is out there roaming the internet makes me a little happier. Keep doing your thing man, may the electromagnetic force be with you.
The Legend! Welcome back!
Best 1 dollar I've spent in a long time. Thanks for posting, NurdRage!
nice to hear you again
So glad for new videos
Holy shit, I was looking for cheap nafion membranes a few days ago and now the man himself releases a video about it.
By the way, this channel is what inspired me to become a chemist. I now work for Agilent and I love my job.
Wow haven’t seen you in YEARS!!!
11 month break, I thought something ... nasty happened, welcome back matey !!
Oh how I've missed this. Was just thinking about how much I missed these videos the other day.
glad to see a new video
First, Arrows vs Armour 2 comes out today on Tod's Workshop, and, now, a new video from the inestimable Dr. NBL. Tis a good day on TH-cam. It's just good to get anything from you again. Hopefully, it won't be too long again, but do what you gotta do in life, and we'll still be here when you do get a chance to make videos. Take care.
Man, I was looking at your channel 2 nights ago, wondering what happened to you. Awesome to see another video!
Welcome back!
I'm very interested in experimenting with novel (and existing) flow battery chemistry, and most of the amateur efforts I've seen use nafion for the separator. It would be very useful to see more about making it or a substitute in the amateur lab context. And welcome back, great to see you again.
Making fluorocarbons is dangerous stuff because the process involves a lot of hydrofluoric acid, either as a reagent or as an end product. Hydrofluoric acid is a major health risk as it is both corrosive and a contact poison. Fluorine gas will also directly decompose into HF on contact with water, so trying to make small fluorocarbons and work from there via direct fluorination is also not safe in an amateur context. In theory you might be able to start with commercially available refrigerant and work from there, but anything going wrong would risk fluorine gas or HF buildup which would be very dangerous.
Not to mention that polar fluorocarbon derivatives like Nafion are what the news is calling forever chemicals because they never degrade in nature and build up in living things because they're ionic. Any waste products (because nobody's going to be 100% in getting their components into their yield) would be incredibly hard to dispose of properly and would turn your lab into a brand new candidate for a Superfund site. Even disposing of a Nafion membrane can be legally problematic depending on local regulation, with the ultimate failsafe being incineration in a facility equipped to scrub out the HF released by thermal decomposition.
Ahhh good to see you back
Welcome back on TH-cam! :)
