During the industrial extraction of titanium, titanium(IV) chloride vapor is reacted with molten magnesium at high temperatures under an inert atmosphere:
TiCl4+2Mg→Ti+2MgCl2 \text{TiCl}_4 + 2\text{Mg} \rightarrow \text{Ti} + 2\text{MgCl}_2 TiCl4+2Mg→Ti+2MgCl2What chemical change does the titanium in titanium(IV) chloride undergo during this reaction?
It is oxidised.
It is reduced.
It is neutralised.
It is decomposed.
