What is formed when you leave iron (II) sulfate in plain air?

It was the question I found in textbook. Assuming that air is oxygen I solved it this way:

$$\ce{FeSO4 + O2 -> Fe2O3 + SO2}$$

But in my textbook it's given that iron  (III) sulphate is formed $\ce{Fe2(SO4)3}$.

Or does $\ce{Fe2O3 + SO2}$ form $\ce{Fe2(SO4)3}$. How is that? Am I wrong? I find formation of iron (III) sulphate highly doubtful.

What is formed when you leave iron(II) sulfate in plain air?

Knowing that iron(II) is easily oxidised to iron(III), and assuming that the reactive component of air is oxygen, I solved it this way:

$$\ce{FeSO4 + O2 -> Fe2O3 + SO2}$$

But in my textbook it's given that iron(III) sulfate, $\ce{Fe2(SO4)3}$, is formed. Is this because $\ce{Fe2O3 + SO2}$ react to form $\ce{Fe2(SO4)3}$?

But in my textbook it's given that Ferric Sulphate is formed $\ce{Fe2(SO4)3}$.

Or does $\ce{Fe2O3 + SO2}$ form $\ce{Fe2(SO4)3}$. How is that? Am I wrong? I find formation of Ferric Sulphate highly doubtful.
