Considering Ellingham diagram, which of the following metals can be used to reduce alumina?

Options

A $Mg$
B $Zn$
C $Fe$
D $Cu$

Correct answer

A. $Mg$

Step-by-step solution

$Mg$ has more $( - ve )\Delta G$ value than alumina.

So it will be in the lower part of Ellingham diagram. Metals which has more $( - ve )\Delta G$ value can reduce those metal-oxide which has less $( - ve )\Delta G$ value.
