POshtrve power.09. Why is aluminium extracted from alumina (Al2O3) by electrolytic reduction and not byreducing with carbon? |
|
Answer» The bond between aluminium and oxygen is more stronger for carbon to reduce oxygen from it hence carbon cannot be used a reducing agent . To reduce Alumina (Al²O³) so as to obtain aluminium, electrolytic reduction is done, with the help of electricity ,aluminium and oxygen are separated and Aluminium is obtained at cathode. |
