    What happens to the Aluminum and what happens to the NaOH after the reaction is completed?

    IOW I see no more Aluminum, it's gone.

    If I place a tiny piece of aluminum foil into the solution, it appears that the solution is too weak to create Hydrogen.

    Can the NaOH be reclaimed by heating the precipitate, etc?

    Thanks

    As a final product, aluminum hydroxide [Al(OH)3] is formed. The sodium hydroxide acts as a catalyst, so in theory can be recovered. Wikipedia has a nice discussion of the complete as well as intermediate reactions. Search: aluminum NaOH
