Blue substance on surface of H2O+NaCl solution undergoing electrolysis
Hey all! I decided to set up an electrolysis experiment using H2O with NaCl as an electrolyte. (I know about the dangers of chlorine gas, I'm working
in a well ventilated area with proper protection.) I decided to try adding multiple graphite electrodes connected to separate batteries. When I
inserted the second set of electrodes, a blue substance started to form around the edges of the container. Any idea what it might be? I'm thinking it
could be impurities from the water, I had no distilled on hand. I've attached a picture, thanks.

It looks like one or more of your copper wires may be touching the solution, in which case that's copper hydroxide.
