Ok. I have two jars connected with a salt bridge. In both jars I have sodium chloride dissolved into water. I have DC 4.4 volts/ .88 amps running through two large copper electrodes. The current doesn't seem to be strong enough to cause anything to bubble, but i know something is being formed because it can dissolve aluminum and can clean old copper. Is hydrochloric acid being formed or am I in over my head?
