In the reaction `3Mg + N_2 rarr Mg_3N_2`

A

magnesium is reduced

B

magnesium is oxidized

C

nitrogen is oxidized

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
(b) In the given reactiom, oxidation state of Mg is changing from 0 to+2, while in nitrogen it is changing fronm 0 to -3. So oxidation of Mg and reduction of nitrogen takes place.
