I'm planning on using battery acid which I think is around ~30% sulfuric acid. The MnO2 is supposed reduce in acid solution, and the carbon cathode to collect the current.
I have 100% lye, and I'm going to make a NaOH solution.
All of the aluminum won't dissolve right? Since I'm not submerging the whole thing in NaOH, I'm just putting it on top of a sponge soaked with sodium hydroxide solution.
Should this dissolve the oxide layer to expose the aluminum metal so it can oxidize in water?
Also, we don't need a long-lasting cell. And yeah, only single cell.
