Question

At 900∘c titanium tetrachloride vapor reacts with molten magnesium metal to form solid titanium metal and molten magnesium chloride. what is being oxidized, and what is being reduced?

Answer 1

TiCl4 is being reduced and Mg being oxidized

Answer 2

Answer:

Magnesium is being oxidized.

Titanium is being reduced.

Explanation:

Hello,

The undergoing chemical reaction is:

$TiCl_4+2Mg-->Ti+2MgCl_2$

Next, oxidation states are assigned:

$Ti^{+4}Cl^-_4+2Mg^0-->Ti^0+2Mg^{+2}Cl^{-}_2$

Half reactions are as follows:

$Ti^{+4}+4e^--->Ti^0\\Mg^0-->Mg^{+2}+2e^-$

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.
