- Welcome to Episode 5 of Molecular Playground. I turn sugar into the activated carbon! Activated carbon is known for its high porosity and immense surface area, making it pivotal in applications like water filtration and air purification.

my left ear got all the fun...
Great video, subbed. How would you process it further to use for water filtration? Please do a video on that.
I think it's supposed to take an acetone bath to further open it up, but I could be mistaken
I initially did not have plans to do make it into a water filter, but yours and another comment have warranted such a video! Expect it to come out around early-to-mid February since I have another video in the works. Thank you so much for the feedback!
will it also work for filtering VOCs in air?
If a regular/commercial activated carbon filter can do it, this can too given enough processing. This processing includes soaking in sodium carbonate to neutralize sulfuric acid residue, soaking in water to remove salt, baking on high, and integrating puffed carbon powder into a filter (all of which will be shown soon in Part 2)
Awesome video. Subed for sure!
Thank you ❤❤
whats the difference betweet that activated carbon and activated charcoal? if i buy activated carbon on the market does it comes from charcoal or from sugar?
Same thing basically, but (activated) charcoal is usually made from wood. Also some activated carbon marketed as activated charcoal is less pure, but that isn't necessarily the case and depends on the production process and quality of intermediates.
The higher quality stuff is from coconut shells. Also called coconut coir. It is heated like wood. Rinsed with distilled water to remove salts then steam activated. Cody has a video on activating charcoal by steam.
great demonstration. I'm looking forward to that you would some experiments and purify it.
It's no clear to me the role of sodium percarbonate.
What was de problem if your acid was pinkish? Where did the sodium go?
The pink dye is an inhibitor that prevents (or at least inhibits) pipe corrosion. I would rather not have that stuff in my carbon. The sodium percarbonate is an adduct of hydrogen peroxide and sodium carbonate ( 2Na2CO3-3H2O2 ). The hydrogen peroxide in it will destroy the dye. As for the sodium, it becomes bisulfate since there is excess sulfuric acid. Thanks for asking!
Hi sir, please tell me what can i do with this carbone activate?
After soaking it in a baking soda solution, washing with pure water, and baking on high to dry (all will be shown in part 2), you can anything you would do with store-bought activated carbon such as filtering contaminants from the water or air
Can i do it for battry carbone?
No. Batteries use a specific carbon called Graphite. Graphite is a highly ordered form of carbon consisting of hexagonal packed tubes which allow for the conduction of electricity. Activated carbon is rather amorphous and won’t conduct electricity because it’s molecular structure is not ordered.
great video but why is the stereo audio only on the left side?
I don’t understand your question.
@@MolecularPlaygroundHe means, that in headphones, the audio is played only in left one
It must be a headphone issue because I have no control over it
@@MolecularPlayground Nah, it's true I have that problem too, only in chloroform and acetone videos there is stereo sound.
Probably you can fix it in YT reactor, if you want
I know how to resolve your issue! (Assuming you are an Apple user), go to settings. Find Accessibility and go to Audio & Visual tab. Turn ON Mono Audio. See if that works :)
alternatively pass superheated steam through charcoal in an oxygen free environment.
How does the sodium carbonate not neutralize all of the acid making sodium sulfate instead?
There is significantly more sulfuric acid than sodium carbonate.
@@MolecularPlayground So you just added the mixed material in to make your final product?
What was the point in removing the pink/purple colorant, anyhow?
And why not use cheap H2O2 in a bottle?
@hunnybunnysheavymetalmusic6542 The sodium percarbonate does not all dissolve in water, but the hydrogen peroxide in it does. The carbonate is left behind when I pour. The hydrogen peroxide in it destroys the purple dye/inhibitor to clarify it. You could use H2O2 in a bottle and that will clear it up, but I have found that it heats up the sulfuric acid too much. Hot sulfuric acid on the sugar causes it to become a black sludge rather than a carbon pillar. Hydrogen peroxide though is ideal for purifying sulfuric acid.
@@MolecularPlayground I guess that all is quite application specific then.
Well, my curiosity is satisfied.
Where do you get your sodium percarbonate?
Amazon
@@MolecularPlayground hmm okay. Could you try making pure hydrogen peroxide by adding a drop of water and letting it react? Does that work?
It’s certainly difficult because some (not all or even most) of the sodium carbonate dissolves in the water. Maybe, just maybe some type of ion exchange resin could filter out the salts and get a solution with a high percentage of hydrogen peroxide.
@@MolecularPlayground Wikipedia says certain solvents could “leech” out the h2o2 but not dissolve carbonate
Maybe acetone?
You are using a cracked Erlenmeyer flask, this is not a good practice, especially with corrosive and caustic chemicals.
Haha, you are the first one who caught that! I could not clean out the brominated oil from the other flask in time to make this video. (Even now, there is still some residue). Also update, the cracked flask is dead now.
Third one chemical is naco3 or other
It is sodium percarbonate. Sodium percarbonate is an adduct of sodium carbonate and hydrogen peroxide. It is shown as 3H2O2:2Na2CO3
This is an extremely dangerous procedure
Yes, not enough safety and hazard information provided in the video. He's doing it outside without explaining why he's outside. The vapor coming out during the exothermic reaction includes unreacted sulfuric acid and is hazardous to breath or contact anything you don't want damaged. It should be done inside a proper fume hood but eh whatever right? Try this at home kids! Downvoted.
@@DMahalko What is dangerous about this? Sulfuric acid can’t be vaporized unless by very high heat (b.p. 300C) which is clearly not seen here because it didn’t melt a hole in the table. The fumes seem to be mostly water because of the condensation, and the bit of sulfur dioxide and carbon dioxide fumes emitted are quickly diluted by the air. I’d argue this is safer BECAUSE it is outside. Also him doing experiments outdoors seems to be a recurring theme rather than something done specifically. Don’t be a bitter, ignorant stronza because his channel is doing better than yours!
