    Why does aluminium ions react with sodium hydroxide to produce aluminium hydroxide but the reaction of aluminium with sodium hydroxide produces no reaction? what is really the difference and why?

    Aluminium ions have + charges and are not as stable as just aluminium. Aluminium solid is stable and is happy, aluminium ion however has a charge and is attracted to/ attracts electrons. Aluminium is more electronegative than sodium (from the sodium hydroxide) as it has more protons than sodium. Therefore is displaces sodium in NaOH as the OH (which is - charged) is more strongly attracted to the aluminium ion. Hope this helps )
