so after the impurities get separated from the pure substance do we have to do some sort of filtration or separation to get a 100% pure substance
@tonibell17664 жыл бұрын
Yes. Typically vacuum filtration.

This is one of my earlier videos, before I got all of my audio issues worked out. Use the volume knob or headphones! I also have newer recrystallization video on my channel with better audio and animations... check it out!

But how do I know how slowly to decrease the temperature? I mean, I have to put it in the freezer eventually and I'm worried that when I transfer the solvent from a cold water bath to the freezer that there is too much of a temperature gradient for the purist possible product.

My question is, where does the impurity go to?
@ChemSurvival Жыл бұрын
The impurity stays in the mother liqour,, the solution above the recrystallized material. That is usually removed by filtration which leaves behind only the purified solid

Great video! Very easy to understand. I have been curious about FAST cooling of a PURE substance, and can't seem to find any information anywhere... What might be expected to happen? My best guess is that more solvent than usual might get trapped in the lattice structure, but that's as far as I can figure. Could anybody help shed some light on this for me? Or at least point me in the right direction to figure this out myself
@ChemSurvival8 жыл бұрын
+Cody Grant more solvent inclusion - maybe. Smaller, poorly shaped crystals - definitely. The classic inorganic example is glass vs quartz. Rapid cooling of silica gives an amorphous solid with very different properties than one cooled very slowly to get a highly ordered structure.

@tittoomal14688 жыл бұрын
Would this be considered as endothermic (since heat is being added)?
@ChemSurvival8 жыл бұрын
+Tittoo Mal At the end of the process, the system cools, so overall, no it is not an endothermic process. what's more important is that it is endergonic overall, meaning that free energy of the system is lower in the final state than the initial. This is why slow cooling is best, because we want thermodynamics in control of the crystallization.
@enzyme200566 жыл бұрын
No the scheme is exothermic. Overall heat is released from the system into the universe. The reaction is *exergonic*. Products free energy < starting materials free energy. I.e week bonds are being broken and stronger bonds being formed. The reverse reaction would be endothermic I.e endergonic.
