If we want to produce pure aluminum (Al) using AlCl3 as a reactant, what other reactants should we use?

A. Fe

B. Ni

C. Au

D. Li

I Believe the answer is D. Li, Lithium. This is because, iron, nickel and Gold are below aluminium in the reactivity series, therefore they cant displace Aluminium from its strong. However, Lithium is a group one element and is more reactive than aluminium and thus can displace aluminium from AlCl3 to yield pure Aluminium.
