How to separate copper (l) and (ll) chloride

idrbur - 28-6-2019 at 07:04

I tried to make copper chloride by reacting copper hydroxide with HCl. I made copper hydroxide by doing electrolysis of water with copper electrodes.
The result of the process is a mix of copper (l) and (ll) chloride.
So can anyone suggest a method to separate both of them.
Thanks in advance.

Bubble air through it so you don't have to separate anymore.

Add some H2O2 until all solids dissolve.

Dissolve them in hydrochloric acid, then dilute it. The CuCl will precipitate, and the CuCl2 will stay in solution.

I was thinking of adding some ascorbic acid to it so that the CuCl2 gets reduced to CuCl but I can conly find sodium ascorbate. So can i still do it by adding few drops of HCl to the reaction.
By the way thanks for all of your suggestions.
