Hello everyone let's look at the question so in this question it is asked about what separation or solvent extraction so it is a separation techniques solvent extraction okay now we know that solvent extraction is used for separating two immiscible solvents right now so here so in this case so after what solvent extraction is done so the process of solvent extraction is done.
00:35
So in this case what happens, solute will move from one solvent to the other solvent, okay, or original solvent to the extractant solvent.
00:42
Now once solvent extraction is done, what we will be doing is, so we will be going, taking out the two separate layers by both regulating the stopcock.
01:01
Okay, now see here, before we withdraw the solvents, the through stopcock, so first we have to remove the stopper which is at the top.
01:13
Now while you shake or while you do the separation, so here usually the stopper is closed, right? so the separating panel is closed with the stopper.
01:21
Okay.
01:22
Now, so when the separation is done, when the two layers are clearly separated, now we have to collect the two layers in different conical plus for the weaker.
01:32
And to do that, we have to on that stopcock...
