he talks about common mistakes (not removing the stopper) but then goes and does an even bigger mistake, when your separating liquids, one layer goes out the bottom, then you flip the sf upside down and decant the other layer out the top, this ensures that there will be no contamination of the layer that is removed last

You usually discard the aqueous layer. So let a bit of orgo layer into the separated aqueous layer then toss that, What you have left is your separated orgo layer. Dry and purify further as needed.

@thrasha666 LOL great catch. This guy is a fail

@anastasismusic check the density of your solvent, less then 1 and the organic is the top layer, more than 1 and its the bottom

@ Jsoh21 thanks but it's too late :(((( it was a stupid question in one excercise....

[Jsoh21]

@anastasismusic Put some water in it. Whichever layer the water goes into is the aqua layer.

[anastasismusic]

how can we find which is the organic phase and which the aqua phase???
