For a high school Chemistry course I made soap for a project. Before doing this, thank god, i learned that one should never use an aluminum container to mix the lye (NaOH) and water. Now, I need to know why.
I know it eats away at the container but i can't figure out why. It goes against everything I've learned so far. At first i thought it was because Aluminum was, for some strange reason :o , more reactive than Sodium therefore replacing it in the reaction but that turned out not to be true. Does anyone have an idea of why?
