Even the thumbnail dissolving
Sean finally i thought it was me only
Thumbnail missing from thumbnail
Ive seen this on other videos aswell
thumbnail got crispy
Idk why the glitching is so creepy to me
Cody, while I may be your chronological elder, you've taught me so much, and reminded me of so much, and rekindled my love of science over these last few years. I cannot thank you enough for this wonderful gift you gave given me.
19:20 this is hilarious, doing all of the mixing of chemicals, including hydrochloric acid and sodium hydroxide, with your bare hands, but putting on gloves to do the dirty work. Absolutely genious.
Wait, when did he mix in NaOH?

When you're doing math, you gotta get your CrafsMan vibe on!
Cody: Squirts hydrochloric acid into a test tube on a shaky egg carton back with bare hands.
Also Cody: Puts on gloves to write with a Sharpie.
Indeed, the trick to understanding this is to realize that salts in solution are no longer salts, but separate ions. If you dissolve more than one salt, you’ll have a mixture of different ions. Depending on the amount of dissolved ions and how strongly they interact (as you explained, it’s a question of equilibrium), some of them might precipitate out, forming whichever salt is the result of the combination.
I was disappointed that this was not part of the argument. Also, the water is really H+ ions and OH- ions floating around.
Take it back -- he got to it eventually.
Great explanation
@@Digital-Dan "the water is really H+ ions and OH- ions floating around" is it because H2O is a bipolar molecule?
Thanks for another example to show my father when trying to convince him, that stuff from the internet is not only luminum hat rubbish.
like those people who think the earth is round, completely out of their minds
@@luisgeniole369 How should a 3-dimensional confinement the size of the earth hold a whole underground civilisation? 3D is an illusion.
@@luisgeniole369 Ikr? it's well know to be the shape of a velociraptor.
I clicked this video expecting something similar to partial gas pressure, and was not disappointed. Absolutely mind blown !
I struggled with this a while ago when I was growing salt crystals, I prepared a saturated solution of table salt, and for the seed crystal I decided to use a crystal from a run I did about a year prior, however even thouhg the solution was saturated, and I checked multiple times, the seed crystal kept dissolving.
Then I remembered that back in the previous run, the salt I used had yieded some unusual looking crystals, which rather than the usual cube shape, were elongated prisms. At the time I thought thi could bave been result of contamination of the solution by leaving it outside my window but now I am pretty sure that was not normal salt.
Table salt may also contains iodine.
I think I saw a preview version of this on Twitter, and now it blew my mind again. This really is an intuitive explanation for something that is not really intuitive of itself. Great video Cody!
Cute cat. Always enjoy your videos!
I've been watching NileRed so much that I was thinking "not settled out, crystallized" and "oh, don't put the wire in there! Pull a vacuum on it through some celite to purify the solute!"
me watching codys lab: wow cody has a nice cat.
My brain: its a codycat
Third channel confirmed

@@MmeHyraelle Cody'sCat'sLab! 😼😺
This is one of the best explanations I came across concerning this topic. Now I understand Multi-Solute Solutions and if cleared my concept of percipitating stuff out of solutíon.
Thank you so much.
The thumbnail seems to be of a badly compressed frame, you might want to change it
But thanks for the vid, I was thinking about this recently, the periodic table of videos did a video about an argon balloon deflating because the argon was dissolving through the rubber
The thumbnail has personality
I believe the fact that that occurred was his reason for selecting that one, if I have any idea how Cody's mind works at all.
I made sure to take a screenshot of it on my phone lol
When I saw the thumbnail I thought the image was dissolving but now that I have watched the video I realize it is actually crystalizing.
Well done, Cody.

Best chemistry class I've ever had.
Question: How practical, if at all possible, would be a chemical method (based on the principles shown here) to desalinate seawater?
If you inject chlorine gas at high pressure into the salt water it should nock out some of the salt. Then by lowing he pressure you can remove the chlorine. I think it could be more efficient but the issue with dealing with chlorine gas would probably erase any Benifit.
@@theCodyReeder Thanks, Cody!!!
Between this video and the different gasses in balloons video, you give a really good understanding to how averages of random particle motion adds up to be what we see at a macroscopic scale. Great videos!
Easily one of the best explanations for solubility i have ever seen!
Dissolving is more like sublimating than melting, because the dissolved particles move pretty freely from each other like a gas
Please keep these types of videos coming this is why I started watching your channel.
Why are your hands so shaky?
I had quite a lot of caffeine to give myself the energy to film this.
@@theCodyReeder that doesnt sound very healthy. If you need a break you can take one
@@theCodyReeder Yeah Cody, you can take a break if you need a break. We'll all still be here. Please take care.
@Cody'sLab no rest for the wicked. Its warm and plants r sure to grow. I wanna see the base progress.
@@murderyoutubeworkersandceos My dude, really?
the analogy with the magnets was fantastic, you would make a great teacher
21:28 I love how you write Cl as [l and add the bracket in front of it to make it [Cl. I wonder how that worked in your head. Did you notice it at the time?
Thank's Cody, always something interesting! I like the eclectic mix of your videos. I always find out something new but then I'm just a 70-year old kid. Keep them coming.
Hey cody hope you are okay!
Your hand writing and hand shaking worried me a little bit are you okay?
I had a lot of caffeine in my system while filming. 🤷♂️
@@theCodyReeder the tremors worried me too, but if they only happen on high doses of caffeine, that's less worry some. Keep looking out for number 1 brother, no one else will. I love your content and I'm glad your doing better mentally. Keep on doing the next right thing for yourself man!
@@theCodyReeder finally the thing that really worried me appeared in the comments! It's great to know you are fine, man!
And the video was great, of course, thanks for your lessons!
In need of potassium! Love your gardening projects, mars/build homestead project and your treeplanting. Take care!
I am subscribed with notifications enabled. Never got a notification nor a recommendation in the timeline. Weird... Thanks for all you do!!
I understand it as: "How much volume do you need hold a mix of 1 litre of dried peas and 1 litre of dried rice."
kind of? the analogy works better for the alcohol in water demonstration
1.5l ......... The rice absorbs that amount to be fully cooked by which time the peas are held in place by cooked rice!
Your peas will be bullets still though .... you need to soak them overnight ;0)
even tho i'd been watching a ton of your's and nilered's videos over the last half year or so, and i understood the basics (IE you do this and this happens), this really clarified what was actually going on. Thank you for this video, and all the work you do.
13:20 Thanks Cody! TFW I finally understand re-crystallization as a purification process that Nile does pretty often on his channel :-) - it's great to see you teach us some chemistry, AIUI you have plenty to say on the subject!
EDIT: Oh wow and that last bit with the alcohol explains how "crashing" something out of solution works, and also why it's a "lossy" process (you're still managing an equilibrium, just balancing it on the side you want)! Excellent!
is it just me or does the thumbnail look... interesting?
Yeah i got some sort of compression artifacts on it
The experiments dissolved the very fabric of reality. Cody survives unharmed though, because Cody.
It's all the plutonium and uranium he has laying around
Don't play with magnets near your computer?
Every time you release a chemistry video, it is always so darn great. I love learning things that make you think about the world differently.
Glad to see you upload! Long time fan/sub self isolating in Halifax! Needed this !
i majored in chemistry and i never really understood solubility this intuitively until your explanation. thanks and well done!
could you make a video teaching us how to turn cats into scarfs?
You might want to clarify that the cats must not be harmed during the process! 😼😺
I just remembered learning these in high school's AP chemistry. It has been a few years and the knowledge starts to fade away. Thanks for helping me refreshing these knowledge!
You are basically explaining chemical equilibrium in the last part and in the first part about the partition law of solvent extraction and its very intuitively done !!
So could you theoretically dissolve an infinite amount of different kind of salts in a liter of water or is there a limit?
I assume at some point things will start to react and fall out of solution. But if you somehow managed to get an infinite amount of unreactive salts, would they all dissolve in just a liter of water?
Seems like it. Another way of creating a black hole.
Love to see you understand the need for mathematical PPE. Its to often overlooked on RUclips.
this one needs to be watched a few times to really get it thanks for doing this
I love how you break down the science in a way that even my brain can understand, I wish I had you as a teacher back in the day, then I would have understood how fun it actually is! I would have been a geek for sure!
I almost failed chemistry and physics due to teachers that couldn´t explain anything in a way that my Autistic brain could understand, but you, I´m just sitting here, nodding, everything makes sense :) you make things so clear :D 💜
Not that I have any need for this type of knowledge, but I love to learn how things works and why, geek at heart I guess lol
So thank you for taking the time to share your knowledge and explaining it in a foolproof way :D
Half of the time Cody is a mad scientist, half of the time he's a super-hippie and sometimes he's just both at the same time
Nice demonstration, and clear explanation. Thanks for this!
29°C is room temperature?
Where is this room located? Hell?
Utah
That's only 84°F. That's not that hot. It's only about 6°F off of what people usually cool their homes to.
Florida when the AC breaks in summer
Thank you for explaining this. I always wondered why purification by crysyallization worked
A new codyslab video. My week is made!
Hi Cody! Glad to see you’re doing well :) stay healthy out there bud
This vid was actually released on my birthday! a great birthday present indeed.
This was such a cool thing to see Cody, I loved the video.
Buddy is the cutest thing in the world. I love seeing him in your videos!
This video made me feel smart.
Great explanation Codes.
Yall remember when cody str8 up showed us how to make nitroglycerin?
Heck with that, were you lucky enough to catch the Uranium Purification before it got pulled?
first of all Cody thank you for another chemistry video. its why i got interested in your channel. i love the chemistry stuff you post. the other content you post is like a bonus content that is complely off topic. XD. love your channel m8 and love your content. keep it coming man.
Awesome vid!!! Glad you're back!
This video is very helpful to visualise and explain the similarities and differences between melting and dissolving. Thanks !
Does the same phenomenon happen in the dead sea? Is that why the water there is able to contain so much salt and make people float like they're riding a semi-inflated buoy?
2:50 WHAT!? THAT ... what??? I'm so surprised. Thanks cody that DID blow my mind
Fascinating! This reminds me of the multiple liquefied gasses demonstration you did in your video on the law of partial pressures.
Cody a fun fact I learned recently is that no one is truly ambidextrous that everyone will always have a more dominant even if they don’t realize. But that ambidextrous people are just good with hand and great with the other. I just thought that was cool cause I didn’t know that.
Isn't it amazing how water is like, the greatest solvent ever?
Really good video! I never understood how this worked before but you're able to explain it in a really visual way which helps a ton. Btw, when are you going to get back to your wax projects? I was really interested in seeing the distillation of paraffin if you still plan on it
I do something similar to treat my well water. My well water has a surprising amount of dissolved iron in it so to remove it I react it with sodium hypochlorite (bleach) it also has quite a bit of calcium dissolved in it so I can't use calcium chlorite which is more shelf stable because it will clog up the injector/check valves of the injector. The solubility of the reacted iron is much lower causing it to fall out of solution in a flocculant tank and the particles are now large enough to be caught by a sediment filter. The excess sodium hypochlorite sanitizes my water and gives me an indicator as to the health of the system between maintenance intervals.
26 years ago i wondered about this and asked my Chemistry teacher. I got no answer.
With all due respect, I very highly doubt it. It's junior high school chemistry.
This channel will be my replacement for chemistry
I muted the video twice thinking I forgot the water tap open :)
Use bare hand as a test tube stopper with Sulphate solutions. Mad lad.
Thank you Cody! Im a chemial engineer but still this was a very informative explanation to me.
I was just thinking about how crazy this is, but mostly forgot how it works. I probably was reminded bc I was thinking about sodium chloride and monosodium glutamate in the same dish, yt coming in clutch with a recommendation straight outta my brain, as it does sometimes.
I questioned my soberness for 1 min after seeing the thumbnail.
You're a damn good educator, my friend. My density is only equaled by neutron stars, and i get it now. 5 star rating for me.
Awesome, glad to see you back into business, son!
I had to come back and say that this was a good video and thank you Cody.
Best intro you’ve ever made
I have never learned and understood that much chemistry before!
Have you had your yearly physical? Concerned! Love your channel.
This dude handles uranium like if it was nothing but for math?? OH boy nooo, WE NEED PROTECTION FOR THAT! Love you Cory😂❤
Welcome back Cody!
Is it possible to distill the water of diesel exhaust fluid off. Then use the nitrated salts for fertilizer and other stuff.
Scientific ASMR, Thanks Cody 💜
Love the taffy example, really cool stuff Cody!
Cody doing demonstration models is like Doc Brown. "Please excuse the crudity of this model."
We
7:00 when you heat up the water: pshhhhhh
I love your vids! Keep up the awesome work and strive to improve!
Perfect timing for that upload for me, can’t wait to watch
0:36 "uh no dude"
Great easy to follow info.
Took my brains a bit to get in the groove but it feels expanded. or swollen?
Thanks for sharing 🍎
A wonderful video for my daughter (and me!)
Love how buddy was draped around your shoulders hahaha
I ask myself why no university has begged you to teach, then I realized, I'm sure you have had plenty of offers, and you turned them down, for your true calling. Thanks for the vids Cody! You somehow make things more understandable :)
Shoot universities won’t touch me with a 10km rod. They hate me and will do all they can to screw me over.
@@theCodyReeder their loss! You would be a great teacher
Interesting, thanks Cody!
Blew my mind.
6:29 sudden edge dislocation in the salt crystal
Is this a re-upload i remember seeing this and it was not from patreon either
Why did he do the last part with his left hand? Trying to practice?
Wow really interesting ! Thanks a lot Cody !
Thank you for your demonstration on the topic, I am in high school and they make us learn those but you know, not with experiments but only tests. I think with that magnet demonstration and seeing the solutions change, I understand it fully now. And that learning process was interrupted by quarantine and stuff, so extra thanks :D
Btw I think there should be another constant around the product of the concentrations, otherwise there is no sign of change when temperature changes. I guess for simplifying reasons you didn't show it.
And glad to see a chemistry video like the old videos :D
Chemistry major here. I never even knew this. I thought recrystallisation worked because Crystal formation would selectively pull product into the structure and push out impurities, and that would decrease total solute concentration in the water which would further prevent impurity incorporation. I guess those aren’t mutually exclusive and a combination of these effects make sense considering the similarity of my interpretation to this one. But yeah never thought about it like that.
I love that your education videos are the best on RUclips yet you use random magnets instead of expensive molecular models, random camping blankets as your backdrop, and an egg carton as a test-tube display. Bells and whistles are the crutch of lesser men!

Question: What effects, if any, does liquid pressure have on solubility? Can more salts be dissolved at the floor of an ocean than at the surface, for instance? It might make a very interesting video.
