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

Magnesium is being oxidized.

Titanium is being reduced.

Step-by-step 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.
