When the recovered copper was washed with acetone and methanol, what was taken out from the solids?

Question

this is part of Copper Reactions experiment

Answer 1

Stuff that is soluble in methanol and acetone was removed.  This can include organic compounds and some ionic salts.  Without knowing what the other chemicals used were, it is impossible to determine what was washed out.  The copper is insoluble in both, and so was not removed.
