Question

2feSO4-Fe2O3+SO2+SO3 is a redox?

Answer 1

Yes because the oxidation number of De changes from +2 to +3 , this is oxidation.

And the oxidation number of S changes from +6 to +4, this is oxidation.

Answer 2

Answer:

Yes, $2 \mathrm{FeSO} 4 \rightarrow \mathrm{Fe}_{2} \mathrm{SO}_{3}+\mathrm{SO}_{2}+\mathrm{SO}_{3}$ is a redox reaction.

Explanation:

Redox reactions are the chemical reactions where oxidation as well as reduction takes place. In the reaction, iron or Fe is getting oxidised and sulphur or S is getting reduced. Iron on oxidation forms oxide or iron while In FeSO4, we have Fe(2+), S(6+) and 4O(2-).  

In Fe2O3, we have 2Fe(3+) and 3O(2-). So Fe loses one electron to get oxidised. In SO2, the oxidation number of S is 4+. So Sulphur loses its 2 electrons to reduce its positive charge. This means that S is getting reduced.
