Which of the following oxides cannot be reduced with carbon monoxide?

A

`Fe_(3)O_(3)`

B

`Al_(2)O_(3)`

C

`CuO`

D

`NiO`

Text Solution

Verified by Experts

The correct Answer is:
B
Since `CO` can be easily oxidized to `CO_(2)`, it acts as a good reducing agent and can reduce the oxides of less electropositive metals to the corresponding metals:
`Fe_(2)O_(3) + 3CO overset("Blast furnace")rarr 2Fe + 3CO_(2)`
`CuO + CO rarr Cu + CO_(2)`
`Al` is quite electropositive.
