Partitioning Between Liquid Phases

Professor Davis explains the concept of partitioning between immiscible liquid phases. This concept is critical to understanding how liquid-liquid extractions are designed and performed in the lab.

you are amazing, 100 times more helpful than a 1 hour lecture. great animations and explanation. great!

[@ChemSurvival]

So glad it helped you! Thanks for sharing it with others to get the word out about my videos!

[@mariaorsic9763]

Fantastic! The simplicity of your words AND superior graphics makes this easy. I have looked for 2 weeks and found nothing but
unnecessarily complicated garbage. Of course, this includes my professor, my textbook, many other textbooks, and 99.999% of everything on TH-cam. I hope you are well compensated.

[@gideonjeconeah8301]

The explanation is so clear like a pure water, Excelente! my friend

[@ChemSurvival]

Thank you! And thanks for sharing the video with anyone you think it might help!

[@jacelynnsu3536]

I know that this video was made 8 years ago, but today it saved me. I am so incredibly thankful for people like you who make easy-to-understand content like this on platforms like youtube. Your explanation of equilibrium was straightforward, simple, and effective. Thank you so so much and I hope this message finds you well

[@ChemSurvival]

I'm well, indeed. 😁 Thanks for the comment. Glad these videos are still appreciated on TH-cam! I still use many of them in my lectures at Georgetown.

[@illuminatiscientists3145]

Now I have understood the concept... Thank you so much Sir... Love from India 🇮🇳

[@joslyns6671]

:O Best explanation I have seen/heard of partitioning! Also, made my chem lab make more sense (: Thank you!

[@wink7779]

please help me understand also..example we do it for herbal bioactive compound extraction
when we have added the high polarity solutebioactive compound plus water and then organic solvent over it but the solute still remain in aqueous phase, then why to use organic phase what is it use?

[@shreyashishah5288]

Thanks a lot!I was juggling with partition chromatography but very well explained by you.

[@abc-hm1yo]

Thank you for great explanation in simple words and short time 👍

[@sumayyagull7780]

this lecture is much better than 1hr lecture of chromatography

[@deepanjanbasak7643]

Thank you sir for clearly understanding the actual mechanism

[@noorqaiseriqbal1649]

Finally I understand this concept. Thank you so much.

[@ruthbarrientos9239]

Thank you for the video!!

[@stavrinalalounta6366]

thank you ! great video , I have a question though , let's say that we have two liquids that we want to separate , so we should have one component which has a high partition coefficient and for the other component should have a smaller value for the partition coefficient ? how is K related to solubility ? thanks!!

[@arturzych138]

What techniques would one use to measure the amount of solute dissolved in one phase? Conductivity? Separate the phases and then do Column Chromatography for each phase?

[@komyohein5771]

Thank you very much for clear explanation.May i know what is the special device for separation? Which video is the sequel of this one?

[@ChemSurvival]

This video will explain the hows/whys of pH-based extractions and a little bit about the separatory funnel that we use to accomplish the task.

Very nice video

[@FatimaFatima-iy9wx]

Amazing, Thanks a lot..

[@maleriehaskins4167]

Dear Prof. Davis. Very informative video. However, I am curious if the two liquids in the extraction are distilled oil and water, is it necessary to add another matter into the mixture? Is there a way I can extract the oil and water from each other without adding in a third matter?

[@cynthiahou2234]

No it's not. As the oil (hydrophobic) and the water are immiscible, they will form two seperate layers. If you add the mixture into a separatory funnel, the less dense oil will be on top ('organic layer') while the denser/heavier water is below. You can then drain the water layer off by opening the tap of the funnel, and drain the oil into another beaker. :)

Super sir

[@aliamer6413]

thanx for video, i would ask about that if i used partition coefficient for 2-nitrophenol in octanol/water mixture, how i can separate 2-nitrophenol from octanol , i tried by simple distillation but is not separate it??

[@safdarsafdari7289]

does it make any difference if first fill with oil then water , i mean does gravity has any effect on the outcome?

[@TuningFreak23]

thanks for the video m8

[@ChemSurvival]

No problem. Glad you found it useful! Cheers.

[@wanhamizan669]

may i ask, i want to do a liquid-liquid extraction to extract acetic acid from it aquoues solution into ethyl acetate, i want to use 20 wt% of acetic acid to be extracted into ethyl acetate, my question is, how do i determine what is the concentration of my organic solvent to be used for the solvent extraction?

[@dr.alanbrumnd1681]

I Like it! It really helped me to understand the subject better! Leah Fischer sent it to me! :)
