Question

Which substance is oxidised in the above reaction? Fe3O2+2H2​

Answer 1

Answer:

Reducing agents are those substances which reduce other substances (addition of hydrogen or removal of oxygen) and themselves get oxidised (addition of oxygen or removal of hydrogen).

Fe2O3+3CO→2Fe+3CO2

In the above reaction, carbon monoxide (CO) acts as a reducing agent as it reduces ferric(III)oxide(Fe2O3) to form iron (Fe) and carbon dioxide (CO2).

Answer 2

In above reaction, water (H2O)  acts as an oxidising agent as it oxidises iron (Fe) to form ferric(III)oxide (Fe3O4)and hydrogen (H2).

3Fe + H2O →Fe3O4 + 4H2
