Hello,
I would like to know what happend here:
I performed an experiment where i used electrolysis on a copper coin and and a carbon rod in normal tap water with salt (saltwater). I cant remember what was on the negative/positive side of the electrolysis but the coin got really dirty covered in black, and the water went to a darkish green color.
Would be really happy if womeone could explain the reaction and logic behind whats going on here!
Thank you!
