i was working with the electrolosis of water, and i was using copper wires, i ended up with a black, greyish solid dissolved in salt water (i added salt when i started the elactrolysis) im trying to figure out what it is, what can i do to test it for copper? (i cant use a flame, and i dont have access to many chemicals, im a HS student) if you could, it would be nice if you could e-mail it to me at wrestler-tdz@hotmail.com
