A Short Liquid-Liquid Extraction Demonstration

Professor Davis demonstrates the technique of liquid-liquid extraction using colored compounds. This allows students to see how both the compound of interest and the impurity are moving through the system as the extraction is conducted.

Very easy liquid-liquid extraction technique, thanks!

[@omarh9410]

Very helpful, thank you !

[@dancalvano8702]

Awesome video, thanks a tone!

[@paulchibuzor8670]

Two miscible liquids, water and what please?
I didn't get the second liquid

wish yt demo videos could stop putting music over the commentary, can't focus.

thanks!

[@SparshaReddy1111]

what is that tablet looking thing in the beaker?

[@darkhuy96]

that is a hot plate magnetic stirrer

[@midosala8049]

That's a magnetic stirring bar.

why is it seasonal?

[@ChemSurvival]

I thought that would be clear... I'm a lab professor... each fall term we tackle the extraction process. Hence, "seasonal".

[@slytherinda4669]

@@ChemSurvival lol I applied to a seasonal environmental lab tech position that listed liquid-liquid extraction in the description. I found your video to refresh myself on the technique and you immediately say "seasonal" so I was under the impression that for some reason, liquid-liquid technique is only for specific seasons.
