Iron is a transitional element and known as "d" block element. It belongs to Group VIII of the periodic table. It is the first transition series in the fourth period. On the left side of it, manganese is located whereas on the right-hand side, cobalt is found.
What happens when iron is dipped in copper sulphate solution?
When iron is dipped in copper sulphate solution, it displaces copper from its salt.
Fe + CuSO4 → FeSO4 + Cu
The balanced chemical equation for the reaction between iron and dilute sulphuric acid is: Fe + H2SO4 (dil.) → FeSO4 + H2
The properties of iron are:
