How many moles of acidified FeSO4 solution can be completely oxidized by one mole of KMnO4:
Correct answer: B. 5
- A. 10
- B. 5
- C. 6
- D. 2
Explanation
The correct answer is option B, 5. This is because the balanced chemical equation for the reaction between acidified FeSO4 solution and KMnO4 is:5FeSO4 + KMnO4 + 3H2SO4 → 5Fe2(SO4)3 + MnSO4 + K2SO4 + 3H2O.

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.
