Electrolysis
Bauxite
Al2O3Al_2O_3Al2O3
To lower the melting point
Graphite electrodes
Aluminium ions (Al3+Al^{3+}Al3+)
Gain electrons (reduction)
Al3++3e−→Al(l)Al^{3+} + 3e^- \to Al(l)Al3++3e−→Al(l)
Sinks to bottom (denser than mixture)
Oxide ions (O2−O^{2-}O2−)
Lose electrons (oxidation)
2O2−→O2(g)+4e−2O^{2-} \to O_2(g) + 4e^-2O2−→O2(g)+4e−
Carbon dioxide (CO2CO_2CO2)
