AI Thread Summary
The discussion centers on the extraction of copper chloride (CuCl2) from used PCB etchant, specifically ferric chloride (FeCl3). The original poster seeks methods to separate CuCl2 from a solution that also contains FeCl2 after reacting copper with ferric chloride. There is uncertainty about the effectiveness of boiling for separation. The poster expresses a primary interest in extracting copper chloride but is also open to methods for recovering copper and converting it into copper chloride. Alternatives to ferric chloride are mentioned, but the poster prefers to stick with ferric chloride due to its availability.

Greetings all. I was wondering if any of you would know how exactly to extract copper chloride (CuCl2) from a solution of used pcb etchant. I know that when you react ferric chloride (the initial etchant) with copper, the products are FeCl2 and CuCl2 dissolved in a dark colored solution but how would i separate the 2 from there? I don't think boiling would help. If any of you know that would be great. Thanks.

Are you interested just in recovering the copper? Or the copper chloride?

I'm interesting in extracting the copper chloride but if that if not directly possible, I would also like to know how to recover the copper and then turn it into copper chloride.
 
Are you interested in an alternative to ferric chloride? No, I haven't tried it. http://m.instructables.com/id/Stop-using-Ferric-Chloride-etchant!--A-better-etc/

So far, ferric chloride is the easiest obtainable etching solution I have at my disposal.
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
