Question

Hi everyone! My chemistry professor assigned us a lab that we need to make our own procedure to, and I'm not too sure on how to approach it. We're given 250 mL of Copper (II) and Chromium (III), and he wants us to end with two separate flasks of the two different liquids and then seperate water out of those two solutions. We're allowed to do one precipitation and one distillation. This is all the info he's offered, I'm considering using a centrifuge to seperate the copper and Chromium. Any ideas?? Hi everyone!

Explanation / Answer

centrifuge is not the best way to seperate copper and cheomium. ion exchange chromatography is best method to seperate copper and chropmium. First mixture was treaated with Dowex 50*8 strong acid cataion exchange resin, elute with 20% H2SO4 chromium ions are coming then after some time elute with complete H2SO4 remainig copper will come.
