    So I've successfully made Rayon and after filtering I am left with a pale green solution. I want to know what this is.

    I added a small bit of aluminium foil to it and saw the solution go from green to clear and a copper precipitate. It can't be CuCl2 because there were no chloride ions in the mix :/
    The solution is acidic but this is due to the H2SO4 added to yeild the rayon.

    Does anyone have any idea what is this byproduct of the reaction or at least some tests I can do to find out for myself?

    Please help!

    It would help if you told us what your starting materials were.

    There are no paradoxes in relativity, just people's misunderstandings of it.
