If you are trying to separate two substances, let's say you did vacuum filtration and you had one that was soluble.
00:21
One substance that was soluble that could stay in the filter and then one or that's insoluble stays in the filter.
00:31
The other one is soluble.
00:32
It comes down into the flask with the solvent.
00:38
So what if my two things were red and blue, but there were still blue left on the filter? what kind of problems can you run into? what might be happening here is that you didn't completely dissolve the blue substance.
01:00
So in order to avoid that, you need to wash it multiple times.
01:11
So instead of just doing it, rinsing the red product, one time to dissolve everything and then washing it down.
01:20
Now you have that in the filter, dry it again, or even before it totally dries, use more of that solvent...
