Make a Nafion Divided Membrane Cell for Electrolysis
Vložit

- 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 CZcams 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!

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
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 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.
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. :)
I'm here for the air sponsorship.
Dont ever leave us again we need you!
I missed you so much
Holy cow he's back.
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.
Finally some NurdRage
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 .
Oh how I've missed this. Was just thinking about how much I missed these videos the other day.
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
welcome back, i was worried that someone found you and you had to go even deeper into hiding
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!
I knew youtube upload times were high, but ten years is outrageous!
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...
this is the first time i really fell that i understand nafion membranes mechanics! thank you!
Bought time, I've been waiting for this video on...whatever you're making.
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!
Wow!! Welcome back fellow nurd!!
Glad to see you're alright. Thanks for the upload!
You know how I have longed for him for a comeback
I completely forgot i was still subscribed to this channel. The channel name alone took me back in time lol omg 😱
holycrap you're back!
missed this channel so much, im still re-watching old videos
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.
HOLY MOTHER OF GOD HE DID IT
HE POSTED ANOTHER VIDEO
I'm happy to know this man is still alive.
Long live NURDRAGE
Oh my god welcome back, Chem Master! ❤️ your works. Also Electrochemistry is my most favourite part of chemistry
nice to hear from you again. Thanks for still being here.
Just in time to watch it with my tea. Glad to see uploads again!
Nurd Rage,
Glad to see that you are still around…look forward to seeing what comes next
Great to see you back!!
I searched your channel to show my chem students yesterday, now you live XD
The world is healed he uploaded
Well bugger me sideways with a shovel! Welcome back!
Instead of a 👍 , CZcams needs a ‽ For comments like that!
So glad to hear you are alive!
Love to see this channel still being semi active! Miss these videos!
Nurd! Great to hear you again!
Welcome back! Always delightful to see a video from you, no matter how much time between. Thank you for bringing science to CZcams, as always.

Welcome Back :) this video just sparked a few great ideas thanks NurdRage.
You're alive!! Welcome back
No way u actually uploaded again i thought they got you.Keep it up though really entertaining
The Legend! Welcome back!
So glad for new videos
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
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 back! We missed you.
Glad you are back , even if it is partly old content .
