I am running a dc current through a solution of Aluminum Hydroxide and I see a solid precipitating from the negative terminal, and bubbles coming from both terminals. Also, the positive terminal is corroding with little tiny holes in it. What is the solid being produced, and what is happening to the positive terminal. I know that the bubbles are hydrogen at the negative terminal, and oxygen at the positive terminal. I suspect that the solid is Aluminum Oxide, but I cannot find much proof through research.
