During the industrial extraction of titanium, titanium(IV) chloride vapour is reacted with molten magnesium at high temperatures in an inert atmosphere of argon:
TiCl4(g)+2Mg(l)⟶Ti(s)+2MgCl2(l) \text{TiCl}_4(\text{g}) + 2\text{Mg}(\text{l}) \longrightarrow \text{Ti}(\text{s}) + 2\text{MgCl}_2(\text{l}) TiCl4(g)+2Mg(l)⟶Ti(s)+2MgCl2(l)Which substance acts as the oxidising agent in this reaction?
MgCl2(l)\text{MgCl}_2(\text{l})MgCl2(l)
Mg(l)\text{Mg}(\text{l})Mg(l)
TiCl4(g)\text{TiCl}_4(\text{g})TiCl4(g)
Ti(s)\text{Ti}(\text{s})Ti(s)
