MCQ
In the reactions given below, identify the element undergoing oxidation and reduction:
$3 Fe_3 O_4(s)+8 Al(s) \rightarrow 9 Fe(s)+4 Al_2 O_3(s)$
$3 Fe_3 O_4(s)+8 Al(s) \rightarrow 9 Fe(s)+4 Al_2 O_3(s)$
- AAI, O
- BAI, Fe
- ✓Fe, O
- DNone of these
✓
Answer
Correct option: C.
Fe, O
(C) AI, Fe
Aluminium is oxidised because oxygen is added to it. Ferrous ferric oxide redox reactions $\left( Fe _3 O _4\right)$ is reduced because oxygen has been removed from it.
