Vedclass · Answer

(D) Carbon reduction is suitable for metals with moderate reactivity like $Sn$ and $Fe$.$Al_2O_3$ (Aluminium oxide) and $Mg$ (Magnesium) are highly reactive metals.Aluminium is extracted by the electrolytic reduction of molten $Al_2O_3$ in the presence of cryolite.Magnesium is extracted by the electrolytic reduction of fused $MgCl_2$ or $MgO$.Therefore,the carbon-based reduction method is $NOT$ used for $C$ and $D$.

The carbon-based reduction method is $NOT$ used for the extraction of:
