Hi there,
I have a simple experiment whereby I cut a fine copper wire. I then expose the bare ends of the wire to deionized water and apply a bias of about 1V. The +vely charged wire end can be seen to slowly grow as a point to bridge the gap. My question is what form does the copper take as it transfers from one wire end to the other. It must be negatively charged but as far as I am aware copper dissolves in water as Cu2+(H2O)6   

Thanks,
Dan
