Question

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

Answer 1

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.
