In the industrial extraction of titanium, titanium tetrachloride (TiCl4\text{TiCl}_4TiCl4​) is reduced using molten magnesium at high temperatures.

The overall reaction is represented by:

TiCl4+2Mg→Ti+2MgCl2 \text{TiCl}_4 + 2\text{Mg} \rightarrow \text{Ti} + 2\text{MgCl}_2 TiCl4​+2Mg→Ti+2MgCl2​

This can be written as the simplified ionic equation:

Ti4++2Mg→Ti+2Mg2+ \text{Ti}^{4+} + 2\text{Mg} \rightarrow \text{Ti} + 2\text{Mg}^{2+} Ti4++2Mg→Ti+2Mg2+

Explain, in terms of electrons, why this extraction process is classified as a redox reaction.
