    2017-1-27  Aluminium cannot be produced by an aqueous electrolytic process because hydrogen is electrochemically much nobler than aluminium. Thus, liquid aluminium is produced by the electrolytic reduction of alumina (Al 2 O 3) dissolved in an electrolyte (bath) mainly containing Cryolite (Na 3AlF 6). The overall chemical reaction can be written as: 2 Al 2O 3 (dissolved) +3C (s) =4 Al (l) +3 CO 2 (g) (1) + +.... Alumina Aluminium
