What is the product formed when iron(2) & (3) oxide reacts with sulphuric acid dilute each?

Dear student,

The reaction takes place as,

$$\begin{gathered} FeO + H_{2}S{O}_4 \to FeS{O}_4 + H_{2}O \\ F{e}_2{O}_3 + 3H_{2}S{O}_4 \to F{e}_2(SO4{)}_3 + 3H_{2}O \end{gathered}$$
Hence ferrous sulphate and ferric sulphate are formed respectively.
