I have recently run an inorganic reaction, that, upon purification of my target product, left as a bi-product a very concentrated solution of copper
ions, with some chloride and sulfate in it as well.
Can anyone suggest any good uses for this? I have the following copper salts; sulfate, chloride, iodide, aspirinate, nitrate, carbonate, phosphate,
acetate and formate, and a variety of acids, bases and other useful, general purpose lab chemicals as well as a few speciality ones.
I haven't the materials to make a thermite composition from it, though, and have done the usual common experiments involving copper salts (dehydrating
and rehydrating, different reactions, etc.) .....any other ideas? I'd be really appreciative, and it would be a great shame for this amount of
solvated copper ions (in water) to go to waste. Thanks.

Precipitate it with sodium carbonate filter the basic carbonate and dissolve it in H2SO4 evaporate to get copper sulphate.
Bromide complexe and cuprates salt are interesting with copper.

I already have the basic carbonate and the sulfate, but alas have no bromide salts
for anything in the lab. Would love to get some though!

I've used my acidic copper salts with various other dissolved metals from circuit board digestion to dye my concrete planters with. Of course, that's
just me.

I would precipitate the copper with hydroxide and keep the slurry of copper hydroxide after rinsing and drying it. You then have impure copper
hydroxide/oxide/carbonate, which is a nice source of any other copper salts by simply adding the mix to a suitable acid.
