Fe is precipitated out when Mg strip is dipped in
Correct answer: A. FeSO4 solution
- A. FeSO4 solution
- B. CuSO4 Solution
- C. MgSO4 Solution
- D. H2SO4 solution
Explanation
According to the reactivity series, magnesium is more reactive than iron hence it will displace the iron in iron sulphate and form magnesium sulphate, percipitating iron.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
