Answer:
Magnesium is being oxidized.
Titanium is being reduced.
Explanation:
Hello,
The undergoing chemical reaction is:
[tex]TiCl_4+2Mg-->Ti+2MgCl_2[/tex]
Next, oxidation states are assigned:
[tex]Ti^{+4}Cl^-_4+2Mg^0-->Ti^0+2Mg^{+2}Cl^{-}_2[/tex]
Half reactions are as follows:
[tex]Ti^{+4}+4e^--->Ti^0\\Mg^0-->Mg^{+2}+2e^-[/tex]
Finally, as the magnesium increases its oxidation state, it is being oxidized and as the titanium decreases its oxidation state it is being reduced.
Best regards.
