Sorption: A Close-Up View

Just “stuff sticking to other stuff”? There’s more to adsorption. Learn about what happens when atoms, ions or molecules attach to the surface of a substance without entering it. This video discusses how adsorption occurs at the chemical level, including physisorption, chemisorption, ligand exchange/anion penetration, outer sphere and inner sphere complexes attaching in different ways, and role of the hydration sphere.
For a more general overview of adsorption, see our video “Sorption in Everyday Life.”

This 5 minute video was more helpful than 2 hrs of lecture in my AgSci class last night. You have possibly save my butt this quarter.

[@LearningGamesLab]

Thank you so much for this comment. Knowing that we are helping viewers makes it all worthwhile!

[@shihanchen6422]

same as me..LOL

[@jaimecarnerocalderon2896]

Using snacks and cakes as examples are one of the most american things I´ve ever seen in my life. (and I love it)

[@GuerrillaRadio13]

This video gave me the simple explanation of different types of adsorption that I needed. I am one exam away from a Master's degree but sometimes I still need these wonderful colourful videos on KZbin. Thank you!

I can relate...love frm sth india❤❤

[@t_a7923]

Can someone give me an idea on chemistry n physics of nanomaterials. .plzz

[@raziphaz2219]

I haven't even started college yet but thank you for the reassurance! I love watching colorful animated videos to secure concepts but I thought it was considered childish. Now know someone with a masters still needs cartoons sometimes.

[@rafaelevangelista6310]

@@raziphaz2219 I'm in my last semester in a Materials Engineering master's and I have no much background in polymers. But I'm gonna use a residue that is used to adsorb metals in a polymerization process so I needed to know just what the hell was going on with with it in a chemical plant. This type of videos are great for that. When I want to just learn a new concept I see no problem using this type of videos. Then if I need to go deeper I search for a college-level class on the topic online and if I need to actually write something about it, then I go to a book or papers - so I can also use them as reference.

lectures and lessons should be explained like this

Good stuff 👍🏾

I have chars produced from coal. it has more water content than when it was an oxidized coal. I'm struggling to find the answer. Clearly it's not because of the oxygen functional surface groups, because oxidized coal contain more carbonyl than chars, which means oxidized coal should contain more water because of it's hydrophobicity. I read that pores actually affect the amount of water adsorbed more than the functional groups, which agrees with my data that chars contain more pores. But I'm still cannot answer, why chars readsorbs water after being dried (in my case it's carbonization)? what causes it? the papers that I read only explain the advanced stuff as, the effect of pore structure, functional groups, types of water formed and such. but what cause water readsorbed to chars in the first place? can I answer it by saying "as long as char has charged ions on the surface, it can readsorb water. and the amount of water adsorbed is affected more by the active sites available, regardless of the functional groups that exist on the surface."

Beautifully made!

thank you helped for seminar

[@saraswatdey5763]

Lovely video with a great explanation. thank you so much it help me a lots

[@emreberat8712]

that was amazing

[@sofiasoares3671]

Parabéns! Você me ajudou muito aqui no Brasil.

[@harijonoh1118]

a good material to understand nature

[@kellykzk]

Does adsorption can happen without water sphere? I mean, is it possible for the polar non-ionic compound interact with the surface directly by intermolecular forces, without water being present?

[@raziphaz2219]

I don't think so. i'm not a teacher, I'm a student, but here's what I think. In order to be considered "adsorption" it needs to be able to be washed away, and the ion needs to be there temporarily. This can only happen if the ion is not actually bonded to the particle. I think if the water was somehow removed, the particle and ion would actually chemically bond, and that is no longer adsorption.

[@rafaelevangelista6310]

That was very helpful, thanks!

[@98Luthfi]

best. thankyou

[@SmellsFamiliar]

Fantastic video, I don’t have a test I’m just baked and curious bout soil chemistry

[@1chillychang]

LMAO

[@lanceorejas3661]

Hi can I include a part of this video in my powerpoint presentation for school? I’ll completely cite and credit you for your amazing video. Thank you!

[@LearningGamesLab]

Yes, with proper credit, we are always glad for the video to be used for educational purposes!

[@YUVRAJSINGH-tl3ib]

Can anyone tell me the bg music

The fact that all bonding types have 2-3 different names doesn't help me lol
