The oxidation states of `Cu` and `Fe` in chalcopyrite are, respectively,

A

`+2,+2`

B

`+1,+2`

C

`+1,+3`

D

`+2,+1`

Text Solution

Verified by Experts

The correct Answer is:
D
Chalcopyrite is `2CuFeS_(2)`, i.e., `Cu_(2)S + Fe_(2)S_(3)`.
Hene, oxidation states of `Cu` and `Fe` are `+2 `and `+1`, respectively.
